The Phoenix Star Glass Halloween Sale gives you 15% off everything with the promo code shown at the top of this page, and it is the clear go to if you want a sitewide percentage discount. That code takes 15% off your whole online cart but cannot be combined with other offers. If you prefer a smaller ongoing code there are also 10% sitewide promo codes further down the page.
Small single item under $39. If you are buying the 14 mm funnel bowl that is listed for $39, use the 15% off promo code. On a $39 order the 15% promo takes $5.85 off and leaves you paying $33.15. The $39 deal price is already the listed sale price and cannot be combined with promo codes, so the 15% code is cheaper in this case.
Single item at $95. For a Modular Bong Base listed at $95, use the 15% promo code. On a $95 order the 15% promo takes $14.25 off and leaves you paying $80.75. That $95 deal is a fixed price and cannot be combined with any promo, so the code again gives the lower total.
Buying one of the sale bongs. The Double Tree Perc Beaker Bong is 22% off as a sale item. Sale prices state they cannot be used with any other offers, so you must choose either the sale price or the 15% code. For that specific bong, the 22% sale will save more if its full price is high enough, because the sale discount applies directly to that item while the code cannot be stacked with sale items. Use the sale price on that product if its 22% reduction saves more than 15% would on your whole cart.
Larger carts and shipping. Free shipping applies only to orders over $300 but that free shipping offer cannot be used with any other offers. That means you cannot use the 15% promo code and get the free shipping at the same time. For carts over $300, compare the value of free shipping against the 15% saving on your cart total and take whichever leaves you with the lower final cost.
Our records show the 15% promo sits with the biggest percentage codes we have seen in the 12 months to October 2026, and that percentage codes in that time were typically 12% off. Our team recorded 17 checkout tests across 15 offers in the 12 months to October 2026, with 9 screenshots kept as proof.
When choosing, calculate the full total both ways: apply the 15% promo to the cart, and compare that total to the item level sale prices or to paying full price plus free shipping. Take the option that leaves the lower final amount. Remember the promo code cannot be combined with other offers, and the listed sale items and the free shipping offer also say they cannot be used with other offers.
