Snake bags for sheds, explain? Are you thinking of using them for substrate?

I only use snake bags for shipping. I just go to Wal-Mart shortly before babies start popping out, buy a couple yards of fabric for $1.00-$1.50 per yard. Spend 1-2hrs on the old trusty sewing machine and make all the snake bags I need for the year in small to med sizes. It only takes me 1-2hrs to cut and sew them all up and cost is a fraction of the reptile suppliers. A small 8X12 bag cost me about $0.08-$0.10 compared to $0.60-$0.75.

Same thing with insulated boxes, just go to Uline for boxes and Home Depot for insulation. I make my own 12X9X6 insulted boxes for about $1.00 compared to $3.50-$4.50.
