Hi there,
I am keen to buy a new z fold 6 (or flip 6), hopefully from Samsung assuming they will be doing some big black friday sale.
I have been reading all the comments about stacking different discount codes, trade-in boosts and etc, but not sure what will be the best and cheapest way to stack discounts strategically.
I am currently using samsung phone A55, I could trade that in or I also have some old samsung phones in drawers I could trade-in (A53 and S10).
I have never bought anything off samsung website directly - I believe there's some new member and app 10% discount codes? Should I sign up and download app now for this? or wait until there's confirmed sale?
I am also a public servant so I do have a government work email address I could use in EPP? I have never tried EPP either, so not sure how it works either, but reading some latest updates, EPP no longer allows you to stack codes?
I also have AMEX card, so that extra $100 discount over $500 would be handy.
Is there anything I have missed? Any kind recommendation on what I need to do now to prepare for the sale?
I know PB tech currently has flip 5 on sale for $897 and I can get this by duty free for $826.80. Should I grab this deal? or is it definitely worth waiting for a better black friday sale deal directly with samsung for flip 6 or fold 6?
Look forward to hearing some good advice from our smart cheapies fellas!

As I understand it, the Samsung member's code might take a few days to arrive so it's worth signing up now on the Samsung member. Especially in case they do another 30% off. If you don't have a Samsung device, now is the time to try and get a 10% off code from Samsung store chat/email/phone. Mine seems to have lasted at least a month.
The rest you're probably fine signing up before buying. That said since Samsung site is often buggy and they also can have stock issues, it might be worth signing up sooner than later. Especially for the EPP.
Note that EPP deals are not always posted here, technically Samsung says you're not supposed to talk about them or at least the prices from EPP. So not everyone is willing to post them. (Also because only some can get them.)
Also while others have been fine with the wrong IMEI, I'd suggest you keep a record of the IMEI of devices you might want to tradein somewhere you can access at all times in case you need to do it when away from home or whatever. Likewise your codes should be accessible.
