In Canada they have a CAD$5 McValue meal deal, so USD$3.67 for a McDouble, small fries & small drink. Do they not have similar deals in your jurisdiction?
For what it is worth, I live in Calgary and the McDonalds near me does not have deals like that. There is apparently a huge range in prices across McDonalds in a city, so there may be geographic limitations.
I don't go either, and the price is part of the reason. (I would go for the ice cream in summer, or for their cheap drinks promos).
US McValue meals (my local location, ymmv):
$6 for a McDouble, small Fries, 4 nuggets and small drink.
$5 for a McChicken, small fries, 4 nuggets and small drink.
$2.50 for a McDouble itself.
A typical burger + fries + drink at McDonalds where I am in the US is now about $20. You can get something much better quality (& larger size) at FiveGuys for same price, and even some nice quality restaurants have lunch specials that cost the same.
McD was never good, but when it was $10 it was still an OK occasional convenient lunch option. At $20 there is zero reason to go there.
