The rub for me is that the sheets I get have the manufacturing date printed in big block letters. The stuff I installed two weeks ago that I paid $10.47/sheet for were made on April 1. The stuff I installed last weekend, that I paid $12.74/sheet for were made on March 3...
This is a typical ploy of merchants - they mark the prices on all of their inventory to reflect standard cost + markup from the most recent purchase (or order) - unless the purchase price drops, in which case, they do nothing at all... With a company as large as HD, that simple ploy can net buckets full of profits, even before the higher-cost stuff even arrives at a store for sale...
Further irritation comes with the fact that I have ample space to store my entire project's worth of materials, but I decided to just buy the stuff 20 sheets at a time, because that's what will fit in my truck (side-mount toolboxes are wonderful, but they **** at times like this...). Had I known, I'd have purchased 100 sheets 4 weeks ago and brokered a free (or nearly free) delivery from HD, which is about 4 miles from my shop.
Oh well - maybe I'll get really lucky and it will be $14+/sheet this weekend...
Drywall was considered, but ultimately rejected. While it's a lot less per sheet than OSB - 1) you can't hang stuff on it as easily as OSB, 2) To make it look nice requires a lot of mud and tape, 3) I HATE to mud & tape drywall, 4) our lease allows us to remove the entire build-out of the space when we vacate, and you can't take down drywall, you have to tear it down. Of course, OSB is never going to look as nice as drywall, but I think I can live with that.
Of course, when that decision was made, drywall was about $5/sheet and OSB was just over $8/sheet...
