OMG - I loooooove Robertsons jerky! They aren't local for me, though, so I pay out the nose to have it shipped. Sometimes they run specials - free shipping with 5 pounds of jerky. Yes... I have ordered 5 pounds of Robertsons jerky and used the "excuse" of free shipping to justify it to my hubby.
I have the opposite problem as OP - all the jerky I can find locally is way too tender and soft for me - imo, it isn't jerky unless your dentist gets po'd at you for eating it.
