SodaStream's headline promotion is 25% off your favorite flavors, making it the best starting point for most shoppers looking to stock up on flavor variety. The deal applies across a wide range of flavor products, and combined with other offers on the site, you'll find the right discount for almost any basket size.
For flavor purchases of any size, the 25% off your favorite flavors deal is your best bet. If you're browsing flavors and want the largest discount available, compare this with the 25% off bestselling items and 25% off accessories deals—whichever applies to your specific items will give you the same savings rate. The general 10% off sitewide is also active, but 25% will always beat this.
If you're buying sparkling water makers, skip the flavor discounts and go straight for the hardware deals. Up to $70 off selected sparkling water makers is the strongest offer for these machines. If the model you want isn't in that promotion, check whether it qualifies for up to $50 off selected sparkling water makers instead. For the E-TERRA starter kit specifically, you'll get a free Fizz & Go metal bottle with your purchase—this gift bundle offer doesn't reduce the price but adds genuine value to your order.
When ordering cylinders, the extra $8 off with purchase of 4 cylinders applies on top of other discounts, so this is worth stacking with your flavor or sitewide deal. If you're buying 4 cylinders plus flavors, apply the cylinder discount plus whichever flavor promotion gives you the larger saving.
For smaller baskets under $45, free shipping on all orders over $45 won't apply, so focus purely on the percentage discounts. The 15% off sparkling water flavors will save you more than the 10% sitewide deal if you're buying that specific product category.
If you're a first time customer, signing up to the newsletter gives you 10% off your first order. New customers should compare this with the public deals above—if any public promotion (like 25% off flavors or 15% off sparkling water flavors) applies to your intended purchase, that will almost certainly save you more than the newsletter signup discount.
At checkout, only one discount applies, so always compare what you're buying against the available offers and select whichever gives you the largest dollar or percentage saving on your specific items.
