Query: A Bit More Glue Please!

Along with my new Shop Vac I ordered two packages of disposable bags. Unfortunately [for me] the bags are defective. Too little glue was used on the seams causing them to rupture within two or three uses. With no bag to catch the debris, the vac filter gums up and loses suction. My 30 day return privileges expired before I discovered the defect in all of the bags I purchased. Amazon has no mechanism in place that I could find to alert them of the problem. Great Shop Vac! Worthless bags. Skip Amazon and buy them locally.
