I used these a lot and was happy with them, but then they started getting pricy. I was delighted to see them for $48.50 in the Kleen Rite catalogue so ordered some. Got them in and sold one right away and put the others instock. Well we got out invoice from KR, and guess what? There was a small typo in the catalogue. They really cost $148. No one told us when ordering and so far they will not honor the price for even the one I sold. I have always had a secret desire for these catalogue places to self destruct. This doesn't do anything to change that. They have to know that they priced the item way low and don't tell you that. I guess that the only good thing is that you don't have to press 1 for freaking English, like the great catalogue place in south Florida. Some days I swear I would rather be selling Slurpees at the Circle K. At least then I wouldn't be losing money.
