do shop checkers kill dumps?
i heard a guy tell me first hand they dont
and a guy tell me first hand they do
so which is which man.

Ofcourse they do lol. Never check dumps on a checker, find a seller that has a replacement policy of an hour or so and check dumps manually, if you have to mark the cards so that you know which card has which dump and replace the bad ones on the go. That way you will filter out shitty sellers and find a good one that actually has good info and the one that you can trust buying bulk without checking and killing dumps. Cheers !!!

If you really want to see if a checker is killing your cards try it on one of your own cards and trust me checkers kill them faster then anything i even had a prepaid bank security team calling me when I used a checker on it huge red flag!

Good advice this from @1nf3rn0

Think like this, most of the time you get 1 swipe out these shitty shops work anyway, so if the checker goes (00) thats your 1 swipe. I've had checker "activate" dumps before. like buy dump, use dump (05) at 3 places or more then checker (00) then try again and get (00) in pos. Crazy game you chose to get into, but be smart and have fun!!! cheers... also old dumps will work, just let them rest for a while and try again when you get bored or need gas, or want entertain the opposite sex................
