I still will use the temporary card numbers to avoid any potential hassle, or if I suspect the vendor might try a recurring charge such as an automatic subscription renewal.
THIS is why I do NOT use debit cards. You simply do not have the same protections.
Good info, thanks!
And OP: I haven't heard anything bad from either but haven't used either. Also Modmy3 worth a shot too
