Does anyone have experience selling on eBay?  I have a question. 

I listed some Stargate magazines (found 'em at the library sale for twenty cents).  One girl won all of the auctions (5 magazines for prices ranging from 99 cents to $5.50).   The auctions ended toward the end of last week.  Yesterday I contacted her to remind her to pay.  She just wrote back saying sorry, some things came up, and she doesn't have the money but will pay me in two weeks.  Fortunately, I remembered to wait until payment came in to ship the items. 

My question is, is that considered normal and appropriate behavior by eBay standards?  My impulse is to say "Oh hell no," and relist them.  Now that I lokok at eBay's policies, it's a little more complicated than that, and will end up taking a couple of weeks anyway.  So I'm not sure what to do.  Ideas?
