Second Chance offer Scams on ebay?

Last night I bid $700 on an amp. the high bid ended up to be $936. there were 3 higher bidders than I.

12 hours later I get an email from someone claiming to be the seller saying the high bidder backed out and is offering me the amp for $700.

While I am not 100% sure this is a scam, here is what doesn't seem right

1. the seller found out the winner could not pay within 12 hours?

2. why not offer the item to the 2nd, 3rd, highest bidders?

3. why not offer the item for what the item sold for? $936?

I emailed the seller direct through his auction to see if in fact he sent me this offer. I will wait for his response

I could have some fun with the scammer, since the item listed is local to me.

I beleive another Audiogon member was the 2nd highest bidder as I recall his screen names to be the same.

Just a heads up to always be on the lookout...
