I found Rock n Roller carts on sale at a sight called AudioLines.com The R8 was $95 and the R10 was $105 - for floor demos. Their regular listed price was competitive with other retailers. I attempted to order the R10 floor demo and specifically asked if it/they were still in stock. The sales agent put me on hold, came back and said he demo was sold but they had an overstock, so he was authorized to sell the R10 for $139.95.
That in itself is a good price, but when he added in FedEx shipping it came to about $155. I balked, knowing some retailers will ship that amount for free. He then checked into shipping UPS and said he could do the deal for $135 total and I'd have it tomorrow or Wednesday at the latest.
So, the $105 plus shipping for a floor model turned into a new R10 for $135 complete - a pretty good deal. My attaboy for today goes to Audiolines.com
