Namecheap's headline offer is the discounted domain registration and transfer deal. This is the place to start if you are buying or moving a domain. Here is how the other offers fit depending on what you are shopping for.
Registering or transferring a domain. The discounted domain registration and transfer offer is your main deal. Apply this when you add domains to your basket at checkout.
Buying an LLC plan. Namecheap has two LLC offers running at the same time. The 25% off Essential LLC plan is a fixed discount on that specific plan tier. If you are looking at the Essential plan, that is the one to use. If you are considering other LLC plans, check whether the up to 35% off selected LLC plans deal covers your choice and compare the two discounts in your basket before paying. The percentage offer may save more on higher tier plans.
Adding an SSL certificate. The up to 16% off PremiumSSL Wildcard deal applies to that certificate type. Apply it when you add the certificate to your order.
First time at Namecheap. If you are new to the brand, sign up for the newsletter before you start shopping. You will receive special offers and promotions that may give you additional savings on top of the deals listed here.
Namecheap's checkout allows only one offer to apply at a time for each product type. When you have multiple options available for the same item, add it to your basket and try each offer code or deal in turn, then pick whichever produces the larger saving on the order summary. For example, if you are buying an Essential LLC plan, test both the 25% fixed discount and the up to 35% selected plans offer to see which saves you more money on your specific plan choice.
