I would have written them a cheque for the full ammount, and it would have bounced.... Ofcourse if they are in Latvia and I'm back home they may struggle to do much about it. I would eventually pay them their $9 after they've spend a good deal more than that chasing me for it.

If they charged a fair price to begin with I would gladly pay it in cash and say thankyou..... Ofcourse, it wouldn't happen because I'd fix it myself anyhow.
