PLEASE SEE MY BRIEF RESPONSES IN CAIPTALS BELOW THAT I HAVE INSERTED WITHIN A COPY OF YOUR POST ...
Did you know you can edit the categories in bulk? You can do it for both ebay's categories and your own store categories. I totally agree with what everyone else has said about categories. I saw you had screen filters and scissors under Pens, so you most likely won't sell many of those two items because they won't be seen. When I want to buy something like printer cartridges, I browse that category first and then put in the keywords I'm searching for to narrow it down. A lot would search that way and your cartridges would never be seen if they're not in the right ebay category.
REPLY - VERY GOOD POINTS AND TAKEN ON BOARD
I wouldn't buy your cartridges because of your appalling pictures - my first reaction would be "what have they got to hide?", or I'd think if you're that sloppy and inefficient with your pictures, how inefficient and/or uncaring are you when it comes to sending the right products out? EVERYTHING has to look professional if you want people to take you seriously. I make allowances for private sellers clearing out the garage but not for a shop. Just work your way slowly through everything and replace the worst pictures first.
REPLY - I WILL BE REVIEWING ALL MY PHOTOS
I also noticed some of your Collins books only show the cover, which is fine if you know exactly which book you want, but for someone not happy with their current book and wanting to see what else is available, they need to see a view of the pages as well. It's not enough to say "5 money columns" - is it 5 per page or 5 per double page spread? You have to cater to everyone because a lot of your sales will come from the people who didn't know until they saw your pictures. The only way to get the edge on other sellers is to offer something the others don't, and it may just be extra details, or postage weights (see further down).
REPLY - IT DID NOT OCCUR TO ME THAT EBAY BUYERS LOOKING AT STATIONERY (LIKE COLLINS PRODUCTS) WOULD NOT KNOW THE PRODUCT ALREADY ... VERY GOOD POINT THAT I WILL ACT ON.
A lot of stationery sellers work on a very low mark-up and rely on volume sales to make their money. Ebay and b&m shops are completely different, especially when it comes to items with expensive postage. Some buyers may not worry about buying from the cheapest seller but a lot of the cheapest sellers (who are also extremely reliable) have a huge following and get a lot of repeat business, so you may find it hard to break into the market if you can't match their prices and service. Comparing yourself to Officeworks is irrelevant - you need to compare yourself with other ebay sellers of the same goods (sellers who get lots of sales).
REPLY - I HAVE TRIED TO COMPARE MY STORE WITH OTHER STATIONERY SELLERS AND, EXCEPT FOR ATEGORIES AND QUALITY OF PHOTOS I THINK MY OFFERING IS BETTER THAN THEIRS. AS FOR (sellers who get lots of sales) I DON'T SEE ANY STATIONERY SELLERS ON EBAY THAT ARE GETTING LOTS OF SALES. THE ONLY WAY I CAN ASSESS AND COMPARE IS BY ADDING UP THE VALUE AND ITEMS THEIR FEEDBACK SHOWS COMPARED TO MINE. I FIND THAT ONLY 30.26% OF EBAY BYERS LEAVE FEEDBACK ... THAT IS WITHIN 1% MONTH AFTER MONTH ... SO WHEN I BROADLY APPLY THE 30% FATOR TO FEEDBACK RESULTS AND COMPARE WITH NUMBER OF ITEMS OF OFFER BY EACH SELLER, THEY ARE ALL PERFORMING AT WELL BELOW 50% OF VIABILITY ... MOSTLY THAT SEEM TO HAVE RETAIL STORES AS THEIR MAINSTREAM BUSINESS AND EBAY IS AN ADD ON.
IS ANYONE PROFESSIONALLY SELLING ON EBAY AS THEIR ONE AND ONLY BUSINESS ACTUALLY EARNING EVEN $20 TO $25 PER HOUR, AFTER PAYING FOR THEIR STOCK PURCHASES AND RUNNING EXPENSES?
I'd suggest putting a weight for each item in the description so that people can work out postage for themselves. If postage is $7.45 and the item they're looking at weighs 230g they'll automatically know they can buy items weighing another 270g without it costing any more for postage. Just allow a few grams more for the packaging. You might think this is a lot of work, but if buyers emailed you and asked about combined postage you'd have to weigh the items anyway. Anything that makes it easy for the buyers will help get you sales.
REPLY - I WILL LOOK INTO THIS, BUT MY CATEGRIES AND PHOTOS MUST BE A 1ST PRIORITY.
I'd think seriously about your store name in the next four weeks. Names that have a message about bargains or cheapest or deals make me run a mile, for several reasons. One reason is that it sounds as though your products are cheap and therefore poor quality. If you're selling branded products why do you want to sound like a bargain basement type shop that sells unbranded products? Names like yours automatically make me think of a market stall with someone hustling passersby for sales. Because of postage costs you can never sell for bargain basement prices on ebay so there's no point in trying to sound like you can. I can't understand why you use a store name of Payless4 cash because 99.9% of people on ebay use paypal, and buyers don't trust sellers who insist on bank deposit (cash). It almost seems like false advertising to me.
YESTERDAY I CHANGED MY STORE NAME TO "AFFORDABLE QUALITY BRANDED PRODUCTS" AND TRIED TO CHANGE MY USEDNAME TO THE SAME BUT EBAY MADE IT ALL ONE WORD AND ALL LOWER CASE. APPARENTLY I CANT CHANGE IT AGAIN NOW FOR 30 DAYS.
The most successful sellers I know of in office supplies have simple names - names that people will remember so they can find them again. You need your products, prices and service to speak for themselves, and I always wonder what's wrong if a seller tries to promote themselves any other way. Why not call yourself something simple like "The Stationery Cupboard" - it tells people what you sell, they'll remember your name for next time, and it's easy to say. By the way, I'm glad you can at least spell stationery correctly! Paper = stationery.
REPLY - COMMENTING ON LAST BIT FIRST ... I ALWEAYS REMEMBER IT AS E = ENVELOPE = STATIONERY (LOL)
I HAD CONSIDERED CHANGING MY STORE NAME TO SOMETHING LIKE "THE STATIONERY CUPBOARD" BUT I HAVE ALMOST LANDED A WHOLE NEW SUITE OF DISTRIBUTORSHIPS THAT ARE NOT STATIONERY SO I WILL NEED TO WAIT FOR THAT TO BECOME A REALITY (OR OTHERWISE) BEFORE I MAKE MY STORE NAME DECISION ... ANYWAY, I CANT CHANGE IT FOR 30 DAYS BECAUSE OF EBAY'S RULES.
All this is meant as constructive criticism.
REPLY - ALL YOUR COMMENTS TAKEN IN GOOD SPIRIT AND APPRECIATED SINCERELY
(It's true enough, though. I know I can be pretty self-indulgent at times ^_^ - and I do take it as acompliment anyway, so thank you [and also to didawaywith for the earlier compliment]
