Some minilabs will do 'develop only' of 120 film, cheaply. Some will not. I'm about to try one in Hoboken -Mimosa Digial... don't know their prices.
Of course Dwayne's charges $3.50 per roll develop only and $3 to scan
Processing and printing of color negative film - develop and print - great prices from a trusted name for over 50 years - Dwayne's Photo Service
