I should have looked it up myself since I had a Shippo account. Yes, the do have PMC available and are recommending it for customers that were using the "A" and "B" boxes. I use 3-4 "A"s per month so the next "A" I would normally use I will use Shippo PMC instead. I see I have more than 4 simple ways to keep under .200 cu ft. using USPS boxes.
1. BOX4 7¼X7¼X5 = .197 cu ft
2. RRB-A1 10.125X7.125X5 = .209 cu ft Cut the 10.125 down to 9.50 = .196 cu ft
3.RRB-A2 11.0625X2.5X13.0625 = .209 cu ft Cut the 11.0625 down to 10.25 = .193 cu ft
4. 1097 11.625X2.5X 13.4375 = .225 cu ft Cut the 11.625 down to 10.5 = .199 cu ft
5. 1097 cut the 13.4375 down to 11.75 = .198 cu ft
6. 1097 cut the 2.5 down to 2.125 = .192 cu ft
Or just cut down any regular (1092, 1095 others) USPS boxes you have down to .200 cu ft or less. This means never cutting a flat rate box to size as it will always ship at the Flat Rate price no matter what label you put on it.
Why I have used Shippo sometimes instead of stamps.com (or ebay shipping)
I sometimes rent something that has to be returned and I supply the return box with the shipment labeled to return the item in. Both stamps.com and ebay charge me more to return it than it costs me to ship it. Shippo costs the same. Dave
