You can drop the stuff from the end, too. If 'ups' is optional and
the spacing is variable, then of course handle that with *

$description =~
s/\s*free\+(?:ups)*\s*ground\s+shipping\s*[!]*\s*//i; # or /ig if
needed

Rearrange to suit. But the imporant thing here is to go for what you
need to replace, and not what you don't.
