Here’s an offer where you can score Free Ziploc Bags from your local store using the $4 OTC Network barcode. Just click the link and choose your store from the drop down (don’t select Amazon or CVS) then fill in your info. You’ll receive a text with a link to access your barcode. Scan that at the register to get $4 off your Ziploc purchase and it it’s $4 or less, it’ll be completely free.
