STIHL dealers are a bit more constrained when selling OEM stuff, due to their dealer agreements. But even this varies with the regional distributor. Some have chain sales once or twice a year. There is a famous dealer in Washington State that offers '
buy one loop, get one free', but cannot ship due to the STIHL rules. Some heavy users buy 10+ chains at a time to get a discount. Etc. Oregon and Carlton distribution and sales are less restrictive, so there is more pricing competition. I will bet that guys who have long term relationships with their dealers get better deals than unknowns who walk in the door and complain about MSRP.
You will always pay more if you have to have something specific (brand, model, size, etc.). You will generally pay less if you can be more flexible. Some guys only want new saws, and some guys look for a project they can rebuild cheaply. Same with chains. If you are willing to clean/sharpen/repair chains, and to invest some time, you can often get used chains inexpensively. You can score good deals on sales, and
sometimes on eBay, if it is worth your time. Other times, once you add in shipping costs, eBay is no different than buying local, including sales tax.
Prices like that will make one of those chain tools unnecessary
No way Ambull - you are a 'gear guy' and have to have a set anyway!
