This is $25 more than the BF deal, but still an awesome deal if you missed it. They had a December promo for 10% off which is no longer active, however I used the chat function on the webpage to speak with a rep who said they will still honor the 10% off via refund to CC after completing checkout. They also have a 5% off promo right now using code LIQUAG5. I completed checkout using the code for 5% off and chatted the order # to the rep. They still applied a refund to my card of 10% of list price making this a 15% off deal.
$588.88 - 29.44 (LIQUAG5) - $58.89 (Chat refund) should bring the total down to $500.55
This method should work across all sizes/grain counts if more or less grain capacity than the popular 48,000.
Note: this is deal is YMMV since it's dependent on th rep you chat with honoring the coupon.
Note 2: the refund showed up on my card the next day after purchase and BEFORE shipment confirmation.
