Shop4Tech offers the Mini Portable & Handy Plastic Bag Sealer for $5.95. Better yet, code FF15 cuts it to $5.06. With free shipping, it's a buck under our April mention of a similar model and the least expensive bag sealer we've ever seen. (It's a current low for a similar model by $2.) It purportedly seals almost every type of plastic bag and features a manual closer. Two AA batteries are required, but not included. There is no sales tax (except CA).
