If you're in southern California, they still have a few of the 60# stackables left at Costco in Tustin. They were $26.99 ($29.15 after tax). After getting my six last night, they should still have eleven left there (only one was left on the display, but the others were probably in the back). Luckily all six fit in my '07 Mustang convertible. Also, there were six or seven at the Compton Costco. It's Costco item number 494989.
