went to walmart to get the bogo free tampon pearls and use a $1 off mq. the cashier girl told me that i couldnt do that because thats two mq for one item, i told her no im buying this and getting this for free and using the $1 off mq on the one im buying. she walked off to talk to her manager then came back 5 mins later and rang em up. i asked her so they work? she said the manager told me i could do it this time. so am i wrong? or is that walmart cashiers confusing themselves..?
