Soooooo......

Because I'm cheap, I've been taking advantage of Subway's $5 footlong of the day specials. In the morning, I get a breakfast sandwich (the exact same one every day) which costs $3.95 and a $5 footlong for later. The footlong sandwich changes every day, but it's always five bucks. I always go to the same store.

After a while, I realized I wasn't paying the same amount every day, so I started keeping my receipts. For the last three days, my totals have been:
Tue: $9.29
Wed: $9.71
Thr: $9.31

The sandwiches always total $8.95. It's the tax that varies.

I always get them to go. I always get the breakfast sandwich heated and the footlong cold. For the life of me, I can't understand what's going on. I plan on bringing the receipts to the manager, but I wonder if anyone here can shed some light on this.
