i know this has probably been beat to death on this forum and if so i apologize. in short we own a 2/4 auto / self serv with attached branded convenience store with seperate window tint shop and state DOT inspection center. we recently leased out the store to more expeienced operators allowing me more time to focus on the wash. i am looking for cross promotional ideas that might integrate all four of these seperate businesses. Ex. free wash tokens with DOT inspection, 5 cents discount on gas if you purchase $9 wash, etc. appreciate any and all ideas, failures, success stores, etc.
