Well I buy 100's of boxes a year or so, either from Staples.com, uline.com or from a box company in Baltimore. Now it seems like Staples.com is the best place to get them, as the Quality is as good as uline.com and the price is way cheaper as Staples has free shipping. As for the Perfect box for the haunted House, Fire Brigade etc, well I got 100 of them from a box company in baltimore for $1.00 each he had 100 of them so I got all 100 but the way it looks I will need more. "But back to Staples and Uline. I ordered 25 of the 20"X16"x4" This is the perfect box for the Volkswagen camper, Friends Olivia's House, 6868 batcave, Etc. and I also ordered 25 of the 15"x12"x4" this box is for the Funhouse, and Orc Forge that I have. From Either site you have to buy the boxes in Bundles, 95% are bundles of 25 or 20. So the Price for these boxes from. ULine.com $64.25 Plus $30.28 shipping. $94.53 Total usually you get the boxes 1-2 days delivered. Now Staples total was $64.74 Free Shipping. So for $30 Cheaper Staples.com is the way to go, the only drawback for staples is you have to order $60 or more for free shipping, and it took a week to get my boxes, as I had them shipped to Staples where I go to the Movies, not sure on how long it takes if they are shipped direct to your house. So $94.53 from uline.com or $64.74 from Staples.com and the boxes were the same Quailty.
