First deal posted in my long history on the site, sorry if this is missing anything.

Apply 12% coupon by clicking on banner - discount reflected in cart - edit: 12% coupon may have been targeted via e-mail promo, if so apologies on my end. There's still a 10% coupon available for signing up for their mailing list, which would drop the price to $477.
All time low on Amazon for a new model (and per deals posted on SD) was $480 6 months ago. Breville products are generally excluded from the BBB 20% coupons and you're hard-pressed to find them on sale often, unless they're clearing out stock for a new model. Red/Black finishes are normal price on Overstock, but on Amazon can be had for around $530 (free shipping, not sold by Amazon).
