I tell a funny story and all you people have to say is that you want stuff framed or about how you're turning evil! I have the worst friends!
Dhamps, I get a 25% discount, but it only applies to close family members! You'd have to marry my sister. Also, I'd need to get a sister. That being said, we are having a 50% off sale for all custom frames, and we're having a penny sale for all frames, canvases, sketch pads, and select paints and brushes. Buy one, get one for a penny.
PlanB, custom frames are quite expensive. I've only been working a week and I've seen orders that go up to 750$. Your poster isn't actually an odd size, though. 12x36 is a standard frame size that we carry in the store.
Loop, if that's what you'd like, then continue on. I think you should rise through the ranks and give them the order they need through strict discipline and pain. Become their Sidious.
