Use Coupon code 20OFF937
Zaycon has some of the best chicken/meat, and it is locally sourced. Note it is only available in select areas of the US.
They don't have stores, instead they let you pick up your order from a semi truck on a particular day (there is only about a 30 minute window before the truck moves on to the next location, so make sure you can make it). I know, the description sounds sketchy (borrowed from the previous zaycon deal actually), but they really are a reputable company and they have a great product at a great price. There have been several zaycon deals recently too or research them online. Unlike the chicken deal, this will come in convenient 1 lb packages so no need to post process them.
This btw comes to $3.192 per lb. In my area, this is the price of 80/20. YMMV
