The link wouldn't work for me either, but I googled the banana pi openwrt one link, and found this page which has 3 Ali express pages to buy from:

Whoops, didn't realize it looks like its out of stock.
I never got the appeal of chick-fil-A, I finally tried like 6 or 7 years ago because someone i knew was raving about it. It was so greasy I got sick a few hours after eating it, I haven't had it since. I don't understand how everyone is sitting there eating the greasiest food I've ever had and then pretending like they're not getting the shits an hour later, while they're raving about it online and to your face. Also its not like I eat veggies 24/7 so fast food obviously upset my stomach.. I eat my fair share of pub food, burgers/fries/tater tots, etc...
That, mixed with their political stance, and they can fuck right off.
