Sign up for Red Cable Club through the OnePlus Store app instead of desktop. You can rack up points fast just doing daily check-ins and linking your phone's IMEI. Heads up at checkout, though: the vouchers you redeem almost never stack with instant trade-in bonuses, so check which discount saves you more first.

Their delivery estimates at checkout are pretty optimistic. Standard shipping is free over $99, but honestly, skip the paid priority upgrade. It usually ships via FedEx Ground from California anyway, so it barely saves a day. Just link your Red Cable Club account before buying, they often drop random shipping coupons there.

Don’t ever buy straight from OnePlus without checking their app first. They constantly give random $30-$50 off coupons there that don't show on desktop. Also, stack their Student Beans discount or do the "any device, any condition" trade-in during launch windows. Saves way more than waiting for basic holiday sales.

They take the usual cards plus PayPal. Honestly, just use PayPal at checkout. If you try running a credit card directly on OnePlus, US banks love to auto-flag it as fraud since it processes internationally. Also, don't forget to stack your RedCoins or check Student Beans before paying; it knocks a chunk off.
