Detroit bikes are 25% off today - that puts the (oh-so-sweet) A-type and the B-Type under $400. The C-type is under $350.
Public Bikes are having a big sale - I really like their e-bikes and the D8.
RadPower has Free Shipping today on select bikes ($175 savings) (Blue Radwagon!)
That's most of the damage I can do today. May your temptations be green.
