Oh do I sympathize with you. A few years back my husband bid on ebay for a Pez dispenser (we collect them) and he put in $3.00 but forgot to put in the decimal point, so that made the bid $300. Of course we won the bid and I'm having a panic attack thinking of that much money for apiece of plastic. But thank goodness, the seller did understand about the decimal point and therefore lost the sale. What a relief to lose!!!!!
Sorry your seller wasn't as understanding.
