The 15% off voucher at the top of this page is the lead offer for Popstar Lab, and it is best for single purchases where you want a straightforward percent off across your cart. Use that promo code at checkout to take 15% off products that are not marked as non combinable with other offers.
Small one item buys under $50. If you are buying a single Popstar Volume + Taste at the marked price of $49.99, the 25% off Popstar Volume + Taste sale specifically reduces that item to $37.49 (25% off $49.99 is $12.50, leaving $37.49), and that sale item’s terms say selected items only but also say cannot be used with other offers for some deals; rely on the $49.99 sale price rather than the 15% code for this product. The 15% promo would cut $7.50 from $49.99, to $42.49, so the 25% sale saves you more on this SKU.
Small buys of single lower priced items such as the 3 oz silicone lube for $19.99. The 15% off voucher takes $3.00 off, leaving $16.99 on a $19.99 order, which is better than no discount. There is no stated sale for this SKU, so use the 15% code.
A single Delay Spray purchase. There are two identical 20% off Delay Spray sales listed; both state they cannot be used with other offers. If the spray is on a 20% off sale, that sale beats the 15% voucher. If the site shows the spray at full price and no sale badge, use the 15% code instead.
First order. The 20% off your first order deal beats the 15% voucher for new customers on that first purchase, so use the first order 20% discount rather than the code when eligible.
Subscriptions and recurring orders. Subscriber offers run up to 30% off or 15% off on subscriptions, plus a free water based lube with a subscription. If you plan to subscribe, the up to 30% subscription pricing is the best value for recurring deliveries; the subscription discounts are separate pricing and do not require the promo code.
Bundles and marked deals. The Big O Bundle is offered for $175.96 and several deal items are explicitly not combinable with other offers. Where a price is advertised (bundle $175.96, Volume + Taste $49.99, silicone lube $19.99), you should take the shown deal price because the product terms often prevent combining the 15% promo with those marked deals.
Our records show 24 offers listed for Popstar Lab in the 12 months to October 2026, including two codes and the biggest percentage code was 15% off in that window; our team carried out two checkout tests across two offers in the 12 months to October 2026 and kept screenshots as proof.
Compare the applicable options for the same cart and take whichever leaves the lower total. Note where a sale or deal states it cannot be used with other offers and treat those prices as final; otherwise apply the voucher code at checkout if it yields the lower final price.
