eBay

What company is the best to use when it comes to shipping. I've been using USPS but seem to pay alot for shipping. i now have the buyer pay for shipping and now have no gotten 1 sell. UPS seems to be fairly cheap and less of a hassle picking the ship...

I'm looking to open a ebay store. wanted to get feedback if getting a ebay store is worth it. I'm looking for any positive or negative feedback.(pro's-con's).
