Phones (at least, I don’t know if it also applies to other Samsung devices or not – it may).
Samsung will pricematch sales on phones, providing a promo code for the difference. You just hit up their order support chat and ask about price match, provide the competitor (Best Buy, Amazon), and they will offer to credit the difference after purchase or send you a promocode within 48hrs to apply before purchase (you may have to ask for the second option. Which is the one you Want).
This then stacks with all their other offers such as: EPP/EDU, referral, 10% website automated-cancel-threat-offer, cashback website, and credit card cashback. As well as any trade in offer they have.
This is the best deal around for buying new samsung phones.
Example (without trade-in):
Samsung Note20 Ultra 128GB unlocked: Samsung price $1299. Current Best Buy sale price $1099.
$200 price match code.
5% referral promocode, valid with a new samsung account (if you don’t have/can’t find one of these promocodes I have one. Not posting referral codes in the topic)
10% cancel offer
Rakuten (currently 6%) = $52
Chase Freedom (currently 5UR, or 7.5%) = $65
Final Net Cost: $752 + tax (31% lower than the $1099 sale price at Best Buy).
