Original eBay 20% off CXMASTECH deal
Saw that TGG were having a sale on TVs and found that it has extended to their eBay store. Found a TV previously posted on OzBargain a week ago ($2699) and found that this is cheaper and won't require membership (assuming that of course TGG doesn't remove it from their eBay store). Unfortunately it won't have the same warranty that Costco offers.
Other TVs worth mentioning (and the cheapest comparison I could find at 4 am):
LG 65UF850T 65"(164cm) UHD LED LCD 200Hz 3D Smart TV $2396 - JB Hi-Fi $3448
LG 70UF770T 70"(177cm) UHD LED LCD 200Hz Smart TV $3036 - Appliances Online $4191
Sony KD75X8500C 75"(190cm) UHD LED LCD 100Hz Smart TV $3992 - HN $4994*
*There's a cheaper manufacturer's refurbished version for $3639.44 saving you $352.56.
Don't forget cashback from Cashrewards.
There are some good bargains to be had there if the code works across their full rnage.
