Don't take it personally when a seller "snubs" your offer. Some sellers have a gazillion items for sale at one time, and it may be hard for them to respond to each and every offer/question they get.

I usually sell 7 items a week on eBay, and sometimes I would get tons of questions regarding my items. As much as I would like to, I can't log-on to my eBay account everyday to answer questions, but I do try to make an effort to answer and reply to all queries from buyers in a timely manner.

If a seller is rude to you, move on. There's not much you can do really. He's the one who lost business anyway, not you.

... and I have been sniped on so many of them!

I agree it doesn't make sense when the stores all base their prices on the other guys. A smart move would be to undersell by a few dollars while going a couple dollars over the average auction price to turn a profit on someone who doesn't want to risk being sniped in auction. I have sold alot of the older stuff in auction. For instance I aquired an extra Natasha Romanoff. Did I really think someone would pay $75? No I auuctioned her and got a little over $40. I've put offers on Banner and Creed that got turned down immediately even though they don't fetch $125 in auction ever that I've seen. So I understand your point of view. Haven't I heard that definition of insanity at some kind of meetings?
