BESTFACTOR is running a 30% off subscription sale, which is the best choice if you're an existing subscriber buying across the brand's full range. Below, you'll find which offer saves you the most depending on what you're buying and whether you're a new or existing customer.
If you're an existing subscriber: The 30% off subscription sale applies to sports, fitness and outdoor gear and food and drink items across the website. This is your best deal if you're shopping for subscription products.
If you're shopping for specific items: The up to 25% off selected products sale may give you a better saving if BESTFACTOR's chosen items include what you want. This sale applies to specific sports, fitness and outdoor gear and food and drink products, not the full range. Compare the two discounts on the items in your cart: if the 25% sale applies to your products, it will save you more than the 30% subscription discount if the subscription product you're buying isn't on your wishlist.
If you're buying the BF Immune Booster two bottle pack: You get 12% off this specific probiotic supplement. On a pack priced at $100, for example, you save $12 and pay $88.
If you're buying the BF Advanced Weight Loss Pills: This thermogenic fat burner is on sale for $39.71 per bottle. The price shown already includes the discount, so there's no code to enter at checkout.
Compare the offers that apply to your basket and choose whichever leaves the lower total. The 30% subscription sale and the up to 25% selected products sale do not stack together, so pick one or the other based on what you're ordering.
In the 12 months to October 2026, the biggest percentage sale we recorded for BESTFACTOR was up to 33% off in August 2026, so the current 30% subscription offer is close to the best we've seen. Our team tested 2 BESTFACTOR offers at checkout in that period and both worked as described.
