Your barometer ended on the 13th and it hasn't been relisted. If you have already used up your 10 listings for the month, it won't be able to be relisted until next month. At the moment, you can only list/sell 10 items a month. What that means is, if you list 10 items on the 1st and 3 sell, you can't list anything new for the rest of the month while the remaining 7 are still active. Next month if the remaining 7 listings are still active, you'll be able to list 3 new items, which will total 10. If you want to list more than 10 things a month, give ebay a call and ask them to increase your limit.

I'm guessing you have reached your limit which is probably why you tried to relist the barometer and it didn't relist. That's not such a bad thing because if it sells for $8 with free postage, once again you will be losing money. You will be paying money out of your pocket for someone to take your items from you, instead of getting money in your pocket.

You also should revise your listing for the pet pedometer and adjust the postage to what it's going to cost. I would change it to $8 postage. I highly doubt the item will be under 20mm, so it has to be sent at parcel rate. If it sells for how it's listed at the moment, you'll be lucky to make a few cents after you've paid extra for the postage and eBay and PayPal take their fees out.

I hope you don't mind me picking your listings to bits. I just hate seeing people paying money out of their pocket instead of getting money in their pocket because of eBay's stupid recommendations.
