How to buy different designs at the same time

brakthol thought this was worth mentioning said

I put in a support request, but I don’t want to wait 2-3 business days.
Maybe someone here can help?

I got an email with some older designs that are back again, and I’d like to buy some. But I can’t figure out how to combine them into one order.
I want to buy 4LB3RT, I’m Done Hanging in There, and Mimic.

I can buy them all individually, and I guess pay 3x the shipping cost? Or I can sign up for the membership, and pay just the monthly shipping cost. But I’d rather combine them into one order.

Is this even possible?
