Petcube's headline offer is the 33% off voucher code, which applies to your entire order and works across most of the store. This code is the strongest option for shoppers buying a range of products, though the choice between this and the available sales depends on what you are purchasing and your basket size.
For small orders under $50, the free shipping offer on orders over $50 will not apply. If you are buying a single Petcube device or a small selection of treats, check whether your items fall within one of the running sales first. For example, selected smart pet devices are reduced by up to 25%, and selected treats carry 25% off. If your items are on sale, that markdown may give you a bigger saving than the 33% code would. If not, use the 33% off code to reduce your total. Once you have calculated both options on actual items in your basket, pick whichever leaves the lower final price.
For orders between $50 and $100, the free shipping threshold opens up a second variable. If your items qualify for a category sale (smart pet devices, treats, or the broader up to 70% off selection sale), that discount applies before you consider the 33% code. Once you know the sale price, apply the code to see if 33% off the discounted total beats the sale price alone with free shipping added. Work the full numbers so you can compare apples to apples: original price, discount, final price, plus any shipping savings.
For larger orders over $100, the 33% off voucher code typically delivers the biggest saving because it takes a third off everything in your basket at once, whereas the category sales are limited to specific products. Free shipping at $50 and above removes another barrier to value. Use the code on your full order and add free shipping to the final price. The code terms note that exclusions apply, so check Petcube's website if you suspect any items in your cart might be excluded, but for a typical basket of pet cameras, trackers, treats and accessories, the 33% reduction will usually be your winner.
If you are a first time customer and not yet on the mailing list, signing up for the newsletter is worth a moment before you shop. The newsletter sign up offers special promotions and discounts, which could give you an edge on your first purchase. However, since the terms do not specify an immediate welcome discount, treat this as a step to take after you have picked your items and chosen between the code and the sales, not before.
Compare the final prices after applying whichever offer suits your basket. You can use only one discount at checkout, so test both the 33% code and any applicable sale price on your actual items, add free shipping where it applies, and go with the option that costs less to take home.
