Did you know that being a new seller with no feedback you can only list/sell 10 items a month, even though a store allows 200 free listings a month? Having a store doesn't increase your limit. Or do you have another account whereby you can get a limit increase? If not, at this stage you are probably wasting you money with a store until you get a limit increase......unless you'll be selling high priced items with a high profit margin. If you items are of lowish value or have a low profit margin, most of what you earn will be paying for your store, plus eBay and PayPals fees.
