Low cost of living to me means.. not buying audio gear at full MSRP from their stores. Because I can't live without audio gear (no cost of living)
I don't know if this will be considered a contribution or more detriment to your wallet. BUT I myself have saved tons of money with my gear doing the some of the following.
Sign up for EVERYTHING.
Newsletters, e-mail subscriptions, notifications, reward cards, memberships, surveys, sweepstakes (as long as they are all free to do)
I get countless $5-$100 off coupons from all around the universe and have gotten a stack of free IEMs thanks to rebates (newegg mainly) and won a few from just following a twitter or liking a facebook page.
www.slickdeals.net has been one of my biggest winners. Set your deal notifications to what you may be looking for and they'll notify you immediately of any deals.
For instance.. I have Koss as a deal tag.. and I snagged all these for dirt cheap.
Koss KSC75 $2
Koss KEB30 $5
Koss IL200 $5
Koss Porta Pros $12
www.midnightbox.com (grabbed UE600's for $35)
www.buydig.com (grabbed FiiO E10 and E06 for $55 total!)
www.shorelinemusic.com/closeouts/ (cans and great dacs occasionally pop up!)
www.dealzon.com/electronics/headphones (occasionally some good stuff, got my free rebate IEMs here)
lastcall.dailysteals.com/ ($10 M6 and R1's from Meelec)
And check out the outlet/clearance/sales sections.. like at lendmeurears.com
There's a lot more.. but I don't have all my links in front of me (saved at my work/laptop)
Essentially I'm looking to choke my wallet.. but more like a light choke. Something you would do to your over achieving son for getting a hot girl pregnant at 18. You want to choke him for making you a grandpa.. but at the same time.. it's a hot chick.
