C4 Performance Energy Drink 4-Pack for $3.78 w/ Subscribe & Save

C4's Strawberry Blast energy drink drops to under a dollar a can when you stack Subscribe & Save on Amazon — here's whether it's worth locking in.

Under a buck a can for C4 — that's actually a solid price

C4 Performance Energy is one of the more credible fitness-adjacent energy drinks out there, made by the same brand behind the popular C4 pre-workout powder. The 4-pack at $3.78 with Subscribe & Save works out to about $0.94 per 12-oz can. For context, these typically run $2–$2.50 individually at retail or around $1.50–$1.75 per can in multipacks. If Strawberry Blast is a flavor you'd actually drink, this is a genuinely good price per can for a zero-sugar performance drink with caffeine and beta-alanine.

The Subscribe & Save part is easy to forget about

The $3.78 price requires enrolling in Amazon's Subscribe & Save program, which means the first shipment arrives at a discount but subsequent orders keep coming unless you cancel or skip. It's not a scam — Amazon makes it easy to manage — but you do need to remember to cancel or adjust the schedule after your first box if you don't want a recurring order. Also worth noting: this is just the one flavor, one 4-pack. If you want to stock up meaningfully, you'd need multiple orders to hit free shipping without Prime.
