GlacialPure has a 40% off code as its headline offer, giving you a significant saving on water filtration products across the board. Since none of the codes can be combined with other offers or sales, your choice comes down to which single discount leaves you paying the least.
Small orders under $50. If you are buying just one or two items, start with the 40% off code from the top of the page. This beats all the smaller percentage discounts and the fixed $10 off option on selected products. The $10 saving applies only to certain items and saves you less than 40% on most purchase totals.
Orders from $50 to $100. The 40% off code remains your best choice. The 15% off code for orders over $50 is significantly weaker. On a $75 order, for example, the 40% code saves you $30, leaving you with $45 to pay; the 15% code saves only $11.25, leaving $63.75. The gap widens as your order grows.
Orders over $100. The 40% off code still delivers the biggest saving. On a $150 order, the 40% code saves $60 and costs you $90; the second best option, 25% off, saves $37.50 and costs you $112.50. The difference is substantial at this spend level.
Buying sale items. GlacialPure is currently running two sale markdowns: 44% off selected products and up to 34% off selected items. If the items you want are on sale, compare the sale price against the 40% code applied to the original price. The 44% markdown is the bigger potential saving, but it applies only to a selection of products. If your cart contains items eligible for the 44% sale, check which leaves the lower total: the final sale price, or the original prices of all items with the 40% code applied to them.
First time customers. You have access to the 15% off first order code in addition to other codes. Since codes cannot be combined, use whichever single code saves you the most. On most orders, the 40% code will beat 15%, but if your basket is small and eligible only for a specific offer like 20% off sale water filters, do the math. The 40% off code applies to your whole order, so it usually wins.
To choose between the codes that apply to your basket, simply work out what you pay with each one and go with the lowest total. All the codes work online only, so add them at checkout to see the saving before you buy.
