McMurray always seems so expensive. I looked at their bags, and they were just freezer bags, nothing special, right? $15 seems insane for 50 plastic bags- even if you got the grocery store ones and tripled them, you'd still spend only about $12!
I get my bags from Uline. Mine are the S-123 8" x 4"x 18" 2 mil gusseted poly bags that sell for $0.053 each in lots of 1,000. Though I would like to use a shrink bag, the $0.35 per bag seems too costly with already razor thin margins.
