Original 15% off All eBay Plus Items Deal Post. eBay Plus free trial is available to any eBay users, even if you just sign up for a new account (just remember to cancel your subscription right after sign-up, by which you'll still be able to get the full trial length but won't be charged at end date).
Initially the listings from Computer Alliance were going to be posted, but then realise they are cheaper at PCMeal, hence amended.
EDIT 20/09: It looks like the SSD prices are finally coming down (due to more sensible NAND prices and, lol, reduced demand due to intel CPU shortage) from several retailers at shop front as well (can be checked via the staticice search links). While although the listed prices are averagely only within $10 cheaper price than buying at shop front, not big but still cheaper, at least they'll be convenient for those who can't go to the shop and prefer getting things delivered.
The prices after discounts are cheaper than Futu eBay.

For M.2 form factors SATA drives, it is often cheaper to buy it directly from shop's website than eBay listings, http://staticice.com.au/cgi-bin/search.cgi?q=evo+860+m.2+SSD… , or MSY eBay using PLUG5 (which sort of compensates the $5 shipping if the item is >$5) if MSY is among the cheapest listing.
Really hoping for a good samsung 1tb ssd deal!
