So how about this:
1) 1 extra large pizza (Classic Greek) plus 1 free (Classic Italian) ----- $34.90
2) 1 medium pizza (Hawaiian Classic) plus 1 free (Hawaiian Classic) ----- $28.90
3) 4 1.5l bottle pepsi ----- 4x.$2.20=$8.80
4) 2 potato wedges ----- 2x$2.10=$4.20
Total = $76.80
Things like pie/salad are not very practical for so many people, unless you want to pay yourself.
Any objections/additions, please write a comment.
