Met-Rx Shake RTD Chocolate Protein Drink 30g, 12 Count $3.49 add-on

I bought many of the Met-Rx preworkouts that have been available as an add-on item in the last week or so.
I poked around today for a cheap RTD protein drink and found a similar deal on a chocolate 12-pack from Met-Rx. @ $3.49 LINK
Hoping it’s a legit deal – the preworkouts were. Sold and shipped by Amazon.com – Keepa tells me it was $25.72 yesterday.
Max qty to order is 4 cases, like all Amazon add-on items – shipping is free for prime members with any qualifying order over $25.
