the posting date is not always the same as the transaction date, especially if the batch up transactions.

on a side note, I just love it when the vendor "name" on the statement is totally obfuscated and non obvious :'(
the only one immediately springing to mind is FXO threw me for a loop... FedEx Office.
but it happens a few times a year.

once every year or two I file a bogus charge claim only to find out after they research it and dig up a useful company name that I say "oh, oops, yes that was real"

credit card companies should require the actual store name to appear on transaction detail, not the processor or parent company. And the actual transaction date.
