Footnote: Items priced 25.00 and up are great for a store. Anything less and you're best to not use the store..the fee's will kill ya.
You can close a store anytime you want. Ebay charges from month to month, there is no commitment. If you close your store at six weeks, you'll receive a two week credit.
If you use a store, use everything you've got to get your products noticed.
Best of luck,
