Okay, let's make it simple. What are all the costs if I always ship my Deep6 doubles set regs to you for service and I do not have a service plan? For the first 5 years.
You keep mentioning the cost of kits, but Chris says parts are free if I send the regs to you.
You say shipping is $20 or less. Based on some things I have mailed recently, I am very skeptical that I can ship a doubles set of regs, with suitable insurance, for that cheap. But, it's fine to just include "+ shipping" in the costs you lay out. However, can you please specify whether I would be paying shipping both directions or if you are covering return shipping? (again, I'm asking based on always shipping to you for service and NOT having a service plan at all)
