My gocery store sells these too. I'd suggest trying them before dropping $40 on a "pro" pizza bag.
As for holding it... would you want to carry the oversize pizza rack all the way to work and back so you don't have to make an extra trip, or would you ride home, affix the wide rack, then go to the pizza place?
In any case, all you need is some 3/8" plywood and some velcro. The plywood can be cut to a square slightly smaller than the pizza box. Drill holes about 1" diameter or more through which you can thread velcro around the rack's ribs. basically, one end of the velcro strap will be permanently fixed to the bottom of the plywood. The strap then loops around the rack in four places (four corners), through the holes in the plywood to the top, and catches the mating velcro strips on the top. This will secure the plywood to the rack. Then, just use long velcro straps that loop around the pizza box (use 2 or 4 straps) to hold it in place.
This design *could* be modified with hinges so that the plywood folds down on the edges when you're not using it...
