I picked up the wheels yesterday. The plan is to pack them up one day this week and then get them to UPS soon thereafter.
For those following along, the seller noticed one of the wheels was bent, so they offered them for scrap value. To save on shipping, only 3 wheels will be shipped.

I've snagged some free boxes and shipping material from Pier 1 Imports (my local outfit must be breaking all sorts of labor laws by hiring hot girls only). It is also looking like all 3 will fit in one box, which looks like you'll end up paying only $30 shipping.
I'm packing them up now so I'll have the final word soon.
