This aggressive pricing strategy is an attempt by the brewer to stimulate demand as an ongoing boycott dents sales for the sixth consecutive week. 

Twitter handle Ramp Capital spotted the promotion on Saturday that reads, "Easy To Enjoy Memorial Day Weekend ... Get Up To $15 Back Via Rebate On The Purchase Of One (1) Budweiser, Bud Light, Budweiser Select, Or Budweiser Selection 55' 15-Pack Or Larger." 

Before taxes plus the rebate, an 18-pack of beer costs around 17 cents per can. Ramp Capital said, "17 cents per beer is cheaper than water." 

The rebate follows Anheuser-Busch's disastrous partnership with transgender influencer Dylan Mulvaney which sparked a boycott by conservatives. Then when Anheuser-Busch pulled support from Mulvaney, it unleashed a boycott among the trans community.

According to Fox News, citing new data from trade publication Beer Business Daily, Bud Light sales volumes for the week ending May 13 plunged 28.4%, following a 27.7% decline the week before. 

The boycott hasn't been limited to just Bud Light. Other Anheuser-Busch products, such as Budweiser Red, recorded a 14.9% decline for that week, and Michelob Ultra fell 6.8%.
