What is the English synonym for the German word "Sparmeister"?
Solution 1:
If you're looking for a neutral word which doesn't carry value judgements, try "frugal".
If you want a word with fairly positive connotations, try "economical" or thrifty (noun: saver; note: spendthrift is a noun, but it has the opposite meaning to thrifty).
If you want a word with negative connotations, try "cheap" (nouns: skinflint, miser, cheapo).
There are plenty of other synonyms to choose from in the thesaurus, if you start with one of these words.
Solution 2:
A person who is always on the lookout for special deals and offers, especially in retail shops but also in supermarkets, can be called a bargain hunter.
As more choices turned once-loyal shoppers into savvy bargain hunters, clothing manufacturers responded by shifting production overseas to cut costs.
Solution 3:
I think the phrase "penny pincher" would also work here. In the usage I've observed it is more neutral than some of the other suggestions.
Solution 4:
Miser, scrooge, careful with money, thrifty, etc.
