About 4 years ago I opened a store and took a Basic level subscription as it gave me around 250 listings.

When I got close to that limit I expanded up to the next level of Featured store as it was supposed to give around 600+ listings (if I remember correctly).

I'm not sure when the subscription levels changed, but I saw today that the Basic store is now 600 listings and the Featured store is 1500 listings and probably has been for some time.

I've most likely wasted several hundred $$ over the last couple of years by having a much larger store than I actually need as my listings have levelled out around 450-500 items.

Anyway, it pays to check if you're overspending on a store subscription, cos Ebay sure aren't going to send you a reminder to decrease your bill.
