I'm really sorry to see this item discontinued. Most of the time, it worked well for me. Then, it didn't. I called the 800 # and the operator asked me to let him "hear" it. He said the suction was not working right and he'd send me a coupon for another.
Yesterday, Safeway in San Francisco had them for about 1/2 price (free to me with the coupon) but no extra bags to buy. So, I called the 800 # again and was informed they were discontinued and I could mail order the bags from a certain company -- not interested in doing that.
