Just an update, most of the home depots brick and mortar (and online, I just tried to have 400 shipped to me and the UPS guy was super asshurt about having to take the boxes back, but oh well) have now discontinued the
proper ($.67) 17 x 12-1/2 x 12-1/2 size boxes which were perfect for records. If you root around you can find the old size (look for 12-1/2) hiding in the stack, but don't get tricked by the 12 size.
The new small box size is 16x12x12 which is just a 1/2 too small, and it's a total bummer. I'm guessing it saves them money to contract to have the boxes made smaller, yet they are gonna lose us as customers.
I guess U-Haul ($1.40 or so) will be the only option until Home Depot figures out they are selling a lot less small boxes because they are cutting corners, literally.
BOO
