eBay

Ok I'm a tad bit confused. I get some free listings to use. When I use the auction style of sale it simply ends in 7 days without me doing anything and I am not charged unless the item sells. Now people are telling me I would do better to use the buy...

I am getting buyers leaving text requests with a phone number on my sales records. What's with this? When I go to look them up they show as a "non-registered" buyer.
