Check your AMEX account for the coupon associated with your account. Purchase must be made with linked AMEX Card, and must be made after visiting www.houzz.com/amex
and using code AMEX100. Promo requires the purchase be $500 before tax.
Cost of the bike is $602.45 before tax (although there shouldn't be any for most buyers). Shipping is free and will probably take 5-7 days. $100 coupon brings it to $502.45.
This isn't the lowest price ever. That would be $404 back in June at Amazon...but this is the best next price.
Never bought from Houzz before, don't know what they are like.
