gettinglarger:
I find food generally expensive, if I go Burger king I look for multiple offers, shoppings a drag, I get really cheap stuff. Its also hard getting big clothes in Spain, but I found a shop that does xxxxxl stuff
Here in the States, BK is one of the cheapest high-calorie fast food purveyors.  They send lots of coupons just about every week in the "junk mail."  
I used to frequent them and take full advantage.  Two Whoppers or Big Kings for $5 is a bargain.  A family meal combo for $12.99 also can't be beat.  Granted the quality isn't as good as Wendy's, but the cost is a lot less.
