Offers aren't as lucrative as they used to be, but found one this morning on my AMEX BBP for $50 off each $250 spent, up to 3x ($150 total). These are additive across multiple transactions, as I discovered on the last round, so you don't have to order all $250 at once if you want to use the $50 off $150 referral bonus to start.
ETA: Just noticed on an unrelated BBP account that there is a $50 off $150 offer floating around as well, perhaps for customers who have not previously redeemed the offer. Both offers expire 9/30/20.
