For those wanting to get the 211 and purchase 2 spoolmates to get the $400 rebate, and a 3rd spoolmate for free (free spoolmate promo ends July 31), I would advise waiting.
With 20% off, Miller 211 and 2 spoolmates are $1455 OTD (no tax). With the $400 rebate and assuming you can clear $200 per spoolmate, you would net paying $450-460. If you wait for a 30% flash sale (assuming we won't have before the end of July), you would pay $1273 OTD. After $400 rebate and selling 2 spoolmates for $200, you end up being at $460-470.
Being someone who has tried selling these spoolmates, they don't sell fast at all. I've had one on ebay for 3 weeks and it still hasn't sold, and it's the cheapest one on there by almost $10. I did this deal on the last flash sale, and my BIL is wanting one now. I would rather only have to mess with selling 2 of those guys for just a little bit more.
