I received two charges on my debit card 20 days apart, the two charges had a description of "AMAZON MKT 49.95" with the withdrawals being between $45 and $50 CAD. Contacted Amazon, they said that they never charged my card on those two dates. So, someone must've got my number correct... Good thing that I only had $3 left in my account this morning...
