Paying with Bitcoin: 30% off in total

Verified at checkout at Growth Guys (growthguys.com) on September 24, 2026 at 2:44 a.m. EDT: HEALTHYLIFE10 applied 10% off sitewide with no minimum purchase and no product exclusions, taking a $70.00 CAD cart to $63.00 CAD — a $7.00 CAD reduction on an ordinary cart — and on a cart paid with Bitcoin the store's own automatic reduction lands on top of it.

Growth Guys reduces an order by 20% automatically when the payment method selected is Bitcoin. That reduction is the store's, it needs no code, and the cart applies it as a separate line. The question this page answers is whether the two lines coexist, because a cart that accepts one and silently drops the other would look the same until the total is read.

The cart, line by line

LineAmount
HGH – Batch GGC40 430iu Kit, subtotal$430.00 CAD
Store reduction for paying with Bitcoin (20%)−$86.00 CAD
HEALTHYLIFE10−$43.00 CAD
Reduced by$129.00 CAD
Left to pay$301.00 CAD

Both lines are computed against the same subtotal, so they add rather than compound: 20 and 10 make 30, not 28. That distinction matters more than it sounds — a compounding pair would leave $309.60 CAD to pay instead of $301.00 CAD, and the only way to know which a cart does is to read the cart. This reading was taken the same way as every other figure on this site, by the method described here.

What to do at checkout

Apply HEALTHYLIFE10 in the coupon field first and confirm the reduction appears, then select Bitcoin as the payment method and confirm the second line appears before paying. Reading the total before submitting is the whole discipline here, and it is the one step no page can do on your behalf.

The part that can change without warning

A payment-method reduction is a store decision and it has already moved once while this record has been running. The figure above is what the cart returned at 11:03 a.m. EDT on September 24, 2026; it is re-read every day and this page disappears entirely on the day the reduction stops appearing, rather than being left up with an old number on it. The limits of any such reading apply here too, and more sharply: a payment-method total is exactly the kind of thing that settles late.
