Since HD is replacing RL with MS~ Home Depot, Ralph, Martha :), they are giving this stuff away! The gallon size has been marked down from $26 to $13! I got one in Tobacco and one in Black Truffles (with a little extra black added). It took a lot of restraint not to grab the last 7 cans, but I'm probably good on glaze now for about 2 years!
(I've never used the RL metallics, but they are half off as well!)
This is really great glaze, and it will only be available online after its all gone! :)
