I encourage you to re-consider eBay. It’s the largest audience of international buyers and sellers.
I buy and sell on eBay very successfully for many years, as has Donna and her twin sister. I gotta get back to selling after my upcoming back surgery.
Cameras and Lenses: I have bought and sold a few used on eBay. I don’t have any experience with other camera sites, except buying from B&H Photo used dept.
Audio: eBay: bought tube amp, tube preamp, cd/sacd player; yamaha receiver; 2 pairs of AR-2ax speakers, Luxman Tube Amp; Chase Remote Line Controller(s); tube tester; AV Power Controller; 2 Turntables; several R2R tape decks; over 500 R2R tapes
Sold lots of tapes, lps, McIntosh SS amp; McIntosh SS Preamp; Carver AM/FM; Carver Amp; helped a friend sell postal stamps to buyers all over the world.
Buying: I always ask questions and get answers in writing, to have a ‘paper trail’ in case of rare trouble. I’ve had a few over the years, and always got full refunds.
Also, I use my credit card with best protection to fund my PayPal account, to get double protection. The tonearm from Russia, I called the CC company 1st, they assured me I would be covered.
Ship: I always double box and require it: because single box does not qualify for insurance claim if needed. Forget friends and family, pay or split the fee and get the buyer’s protection.
Sell: I have carefully thought out ‘general’ notes, then I add ‘specific’ notes, darn good photos, and encourage questions. I take the time to understand both domestic and int’l shipping costs, weigh stuff, IOW, no surprises to me or buyer regarding shipping cost. Sometimes list the weight and box size, let the buyer figure it out.
UPS Pack and Ship: I have both offered it, and used it. Buyer makes arrangements, seller simply drops unboxed item at local UPS office, buyer pays UPS directly to pack and ship.
I always offer unconditional return/refund. I’ve had only 1 piece of equipment arrived destroyed (my fault that time), 1 tape destroyed by usps, 2 other R2R tapes when I gave full refund even though ….
Feedback supports my 100% rating, if done right it can be fun and rewarding.
I’ve used Facebook Marketplace, to sell tires, buy used bicycles, but that’s all ‘quick, real bargain’ deals, not a good source for selling in my experience.
Hifishark has led me to many other sites, all successfully. I’ve got an account setup to bid on Yahoo Auctions, have the patience to wait for stuff from China, Japan, …..
Professionally, designing and building Corporate Office Space for 46 yeasrs: part of my success was in anticipating what could go wrong, and finding methods of preventing that. Got me ready for eBay!
