Where can i print 24x36 sized posters? Cost?

Did you try Kinko’s?

I second Kinko’s. I’d start there.

Kinko’s, know known as FedEx has a great plan

My Walmart’s photo lab does large posters. I think its less than $12.

also target in billings montana or any other target too.

your welcome

Although you can consider Kinko’s you probably would save some money if you just tried to find a large format ink jet printer. That is what you are looking for. Costs are going to vary widely on the low qty range you are talking about. My guess is @ $30–70. Why the large variance? When you are doing a qty of 1 or 2 you primarily are just paying for prepress time and a little on printing. A lot of printers won’t want to deal with that small $ amount unless it is at a premium. If you ever get to where you want to print 250 or above it would be worth your while to look at offset. Hope this helps.
