I'd been doing Sonics 4 to 6 times a month forever and was usually able to get $10 fees for my locals. $15 if I'd do a late month one and up to $18 for remote locations that I might grab on a route. I grew tired of their food and as part of my overall goal of eating healthier I haven't touched a Sonic or other fast food since last Fall. (I'm down 18 pounds!!)
That being said, I just got email offers for two remote locations for $25 fees! They're both along my upcoming route planned for this Saturday so I grabbed them both. No intentions of eating more than half of each order. Nice surprise, as I've never seen their bonused fees this high.
