I have to agree that having a store is probably not cost effective, for your volume of sales you are not going to be paying less in FVFs than you are spending on the store.

You can list all your items as BINs for 30 days relisting them every month as long as you don't waste money by listing in more than one category.

I would charge a nominal postage fee, I work on $5 per item, so if anyone wanted more than one of your knife sharpeners you could discount the postage. I see no point in having separate listings for different quantities if the buyer is not saving money by buying more than one at a time.

You could list the back support belts as different listings for each size which gives you more exposure.
