I am happy to let you upgrade to the new bag at *very* close to the factory cost plus S&H. I will make little to no profit on this transaction, I am doing this because I care about my customers who have been around for a while and want them to have a better bag then I was able to make at the time. This amount will be considerably less than you paid for your duffle that I sewed way back when. (And to clarify, it's not a trade in, you'll keep the original bag too).
email me at firstname.lastname@example.org and let's talk! :) I'll probably be able to look your order up and confirm in my records, but just in case, if you could have your order info ready that would would be great. I'll run this "idea" from now through the end of December.
