input: [Service] Future website updates when your store is already online [What We Offer] Free support - we will show you how to do the update yourself, if possible, for no cost. For website maintenance updates, we charge $50/hour, billed in 15 minute increments (so a 15 minute update is only $12.50). Custom programming is $75/hour. We always provide quotes and get your approval before doing any work. [Common Practice] 
output: Some carts outsource these updates to unaffiliated developers. This can be highly unreliable in the long-term. Some carts charge $100/hourly with a 2 hour minimum. Even a small, simple update could cost $200! Make sure you know this ahead of time.
