Yes there are fixed costs for everything (somebody's gotta pay for it, right?) The Lit-carts ® cost $40 a piece and you are required to buy them in pairs for $80. There is also a catalog of all kinds of accessories, which may include covers, etc. Not sure about pricing.
Except now they're provided at no direct charge (see earlier in this thread for post and link to the BoE Letter)
And, anyway just three months at $15-a-month poster is more than the capital costs, as per my earlier post in this thread.
That's all folks!
