Hi - I started selling about 5 years ago and did the numbers back then on paying for a store.

Check get out the fees that you can achieve by having a store - some stores don't cost much - but offer advantages like some free listings.

Unless you have a lot of buy it now auctions that you want to run continuously it's not really worth having a store (in my humble opinion).

The store pages are next to useless for buyers - again only my opinion.

If you sell over $50K per month then it's worth looking at the anchor store ($499 per month) - as you can save 1% seller fees and you get extra benefits of fee listings in overseas ebay sites.

Hope this helps.
