I paid a $87.00 per sheet at the time of my last order for 8 sheets of columbia UV-2S B-1 Rotary Birch NAF VC plywood with Pure bond. (UV2S = Pre finished both sides) That included free, rural, delivery.
5 sheets yielded.
13.8 feet of upper cabinets (6 boxes) with 3/4" backs.
1 36" inch sink base. ( I used columbia 1/4" C1, rot maple, prefinished 1 side for the back. This ran about $31.00 per sheet, and was also purebond)
I used less expensive shop birch I had on hand (also purebond) for the two drawer bases, and sprayed the interiors. This ran about $50 per sheet off the top of my head, but I did not buy much quantity.
The cost of plywood, was pretty much insignificant compared to the rest of the job.
The pricing that I get is based on increments of 5 sheets. It is always better to buy wholesale, as the markups found at lumber yards and hardwood retails can be pretty high. Free delivery is also a perk, and they usually sell a whole lot more than just sheet goods (think hardware, solid surface, laminates, edge banding, and anything else you could ever want)
