I hate checkout donations. They're annoying. I always say no, but some people act like I'm the devil. Maybe the OP just doesn't want to deal with that. kind of spineless, but it's annoying.

Just keep on a walking.

Time for you to read and internalize "When I Say No, I Feel Guilty". Sounds like it'll change your life, OP

I feel for you OP, I can't say no because I'm afraid of letting people down, once when I was seven, my mother asked me to take out the trash and I said no and a week later she left me and my dad so I used to think she left because I said no to taking out the trash, I always have a compartment in my purse just for spare change to give to homeless/charities

just think at least your money went to a good cause . good karma for you :)

just say no

A friendly "no thank you" would have sufficed.

Are you informing us that they take cards for donations or telling us that you actually used your card to give them a donation?

You don't always have to give back financially, vaulenteering can be just as helpful.

you shall learn to say nol.
