Vankyo has a strong lineup of promo codes and sales running right now. The featured 40% off sitewide code is the headline offer and works on your entire order, though for returning customers there are also deeper percentage codes to consider depending on your basket size. First time buyers have a dedicated 35% off code, and Vankyo's sale section offers up to 52% off on selected products.
If you're a first time customer buying anything, use the 35% off first order code. This gives you the steepest starting discount available to new shoppers. On a $100 order, for example, this code takes your price down to $65, saving you $35. This code cannot be combined with others, so it is your best single saving as a first time buyer.
If you're a returning customer on a smaller basket, the featured 40% off sitewide code is your best choice. This applies across the entire Vankyo site. On a $80 order, for example, you save $32 and pay $48. This code also cannot be combined, so compare it directly against the other percentage codes below.
If you're a returning customer buying items that are not on sale, compare the 40% off sitewide code against the 22% off code to see which applies to your specific items. On a $150 order, the 40% off code saves you $60 and leaves you with a total of $90. The 22% off code saves only $33, leaving you with $117. The 40% off sitewide code wins on this basket. Neither code can be stacked with other offers.
If you're shopping the sale section, buy from the ongoing sale first. The up to 52% off selected products sale is already applied to prices on the Vankyo website, so you do not need a code. Check which items are discounted, then decide whether those savings beat the percentage codes. For example, if a projector is reduced by 50% as part of the sale on selected products, compare that against what the 40% off code would cost on the original price. If a $200 projector is on sale for $100 (a 50% markdown), that beats the 40% off code, which would cost you $120. The sale savings apply only to marked down items, while the codes apply to the items you choose.
Between the 40% off and 22% off codes for returning customers, the 40% off sitewide code is almost always better as long as the items you want are not excluded. Both cannot be combined with other offers. Work out your cart total and apply the 40% off code first. If that saves more than 22% off the same order would, use the 40% code and proceed to checkout.
