How far apart between 1st discount can you use the next discount..can i get a hole punch..if I buy a $60 n get $30 off..Can I buy a $80 right there n get $40. Off ?

I don't know why this other guy is "sure". Better to just call and ask because it's either allowed or it isn't.

No, they can't be piled on top of each other like that. You have to wait until you come in again to use the next discount.

I'm sure you can. You might have to run outside and come in and ring it up as a separate sale
