On sale and with free postage this works out to a decent deal (+$7 for postage insurance). Saving roughly about $50.
If your after the B550-F version, at the time of posting its on pre-order for $329 with no ETA but other local sellers are also doing a similar price point but postage might kill the deal.
Edit: as pointed out by cnut Asus have $50 steam voucher promo with the purchase of certain Mobo's. See link for more details.
