The XL black cartridge costs 36 bucks and does about 2,500 full size pages.

I've been using the very basic 4.25 x 6 yellow postcards (with plain, black ink) for almost all of my mailings for the past five years, and I don't think I've ever gotten a response rate of less than 5% (at least, none that I can remember).

Full-color on both sides or just black print on a yellow card?

Is it strictly black on yellow, or are there some red punches in there too?

Well I can't if there is no number.I've got my postcards a very simple black and yellow.

I like when I'm at Home Depot getting black pipe cut and someone asks the worker where something is and I take them to it so my pipes can continue getting cut.

BiggerPockets could decide to sell this book on the black market for millions - and that's BiggerPockets' right.

The air conditioner broke and she was trying to stay cool.I inspected a Lonnie Deal that had a pot growing room with black lights.The list goes on and on.What's the strangest/weirdest thing you ever saw?

For black & white, small postcards, I don't think you'll beat their price with no minimum quantity order.
