Over the last 6 months, I have purchased 8 boxes of Hefty Shrink Pak bags. Each box costs roughly $41, for 4-6 bags. THIS IS ABSOLUTELY ATROCIOUS AND COULD BE CONSIDERED ROBBERY AS FAR AS IM CONCERNED. To spend THAT much money on plastic bags is Ludacris to begin with, but to spend that much and receive a product that is essentially useless is extremely disappointing. The quart and gallon size Ziplock bags are 100 times stronger than these worthless things. They either already has small holes in them (rendering them useless) or tore VERY easily while filling them. No, I didn't over fill them. User's recommendation: Buy a different brand....these are JUNK.
