Best Way to Discount Bunnings for TP-Link Deco XE75 3-Pack (Price Beat? PowerPass? Gift Cards?)

Hey all I'm trying to chase a clean discount for a TP-Link Deco XE75 (Wi-Fi 6E) tri-band mesh.

I'm eyeing these right now:

Bunnings (sold by Bunnings, Special Order) XE75 3-pack — $497: https://www.bunnings.com.au/tp-link-deco-xe75-axe5400-tri-ba…

Amazon AU XE75 2-pack — $449: https://www.amazon.com.au/dp/B09SPN9B32?tag=…
(2-pack only; easy returns)

eBay XE75 2-pack — ~$375 (FutureGear): https://www.ebay.com.au/itm/…
(likely parallel import)

Goal: near-full 500/50 in a far room (tri-band backhaul). I only need two nodes, but I’ll buy the Bunnings 3-pack if the discount stack makes sense (can resell the spare).

Questions for the hive mind:

10% Price Beat at Bunnings — has anyone successfully price-beaten this exact 3-pack SKU recently? (I know Marketplace listings don’t count, and competitor must have same item in stock.) Any legit cheaper 3-pack to trigger the beat?

PowerPass — does this SKU get any meaningful trade price, or is it usually the same as retail for networking gear?

Gift cards — best safe source right now for discounted Bunnings eGift cards with PIN (so I can use them online if needed)? ShopBack? Motoring clubs (NRMA/RACQ/RACV)? Any live bonus-points promos at Coles/Woolies on Bunnings cards I should time?

OnePass / Flybuys — worth joining purely for this? Any stackable points/cashback when paying with gift cards?

Alternative play maybe if the 3-pack can’t be beaten, would you just take the Amazon 2-pack @ $449 for easy returns and be done with it? (Two-storey brick place; I can place the deco just before the dead zone.)

Any current stacks, recent success stories or “don’t do X, do Y” appreciated. Cheers!
