If it’s used by Aoshida-US or Hifi-College they both have 1 year warranties and excellent support via the Amazon merchant shipping system (no returning to China) locally. SMSL Factory store does too, but I haven’t done a claim with them as to how they accept warranty issues. Amazon Prime day is just going to be no name brand overstock like every year. Might find something here until the 11/11 Black Friday stuff starts hitting for deep sale prices.
Hart Cables has a 20 percent off everything sale for their 5 year anniversary.

Open box sale going on. Not sure how often these are run, but I got an Instagram ad today because of it.
Possibly a great stacking opportunity coming at Aliexpress on October 1st.
Aliexpress has Choice day sale on October 1st (3am EST) with the big coupons up to $140 off depending on purchase total.
Capitol One currently offers %13 off Aliexpress purchases, including consumer electronics and many other categories.
To activate it, you have to log into the Capitol One site, then click the link and buy on Aliexpress. I’ve used Emo and it works too if you have their browser add-on. I’m waiting for the 1st to see if the discount is still available the moment the coupons go live. With a new warranty doubling a purchase, it could be a good time to buy before the 11/11 sale. That sale is 20 percent off most things, stacking a cash back credit card and coins. You can log in with multiple devices on the same account to claim coins each day too. Fingers crossed that the Capitol One offer is still working when the coupons activate.

In Tampa, Florida currently waiting out the storm to come in. Here’s some good deals, and also at the bottom are some of the factory outlets I check regularly. I buy a lot of audio equipment for the business, but with the airport closed today everything is shut down until Friday for shipping. If it’s from Hifi-College or Aoshida-US they have 1 year warranty on used items, and both have really good support for warranty items. Since the big 11/11 Aliexpress sale is a month away, here’s some good discounts:

For those that are ok with buying from Drop, the Cayin HA-1A MK2 amplifier is for half-price. I’m not into tube stuff but this was always one to catch my interest. Transformer design, beautifully build and able to play with output impeadance. @WaveTheory always talked good about it also.

Sound Rhyme SR9 for $190, seller is a nice guy from my interactions so far:

Summary of reviews I can find on it: Warm, relaxed, with heavy bass but not the best upper mids timbre. YMMV I guess!
