It is a matter of time versus money. It can be worth it to just have the job done rather than take your limited free time to do it. I paid someone to reroof my house even tho I have done roofing and could do this myself because it was worth the money to not spend a week crawling around up there

However most bike repairs, like a tube change or replacing a broken cable, don't take very long to do and it can even save you time because you will not need to make the trip to the store, if you already have the repair part needed. I think a lot of customers that get basic repairs done at the shop, do it for one of two reasons. They don't know how or they don't want to get dirty.
