Thank you for choosing Thames & Kosmos and for your interest in our kits.
For our end-users who wish to purchase replacement parts for their kits, we are happy to confirm that you don't have to create a PayPal account in order to pay your invoice, as PayPal offers the option to check out as a "Guest." Here are the instructions on how to make your payment without creating an account.
Click the link in the email you received to be brought to your invoice. You'll see a page that looks like the screenshot below. Click on the blue "Pay $ (amount due)" button in the upper-right, which I have highlighted below in red.
A pop up will appear, asking you to log into PayPal. If you don't see a pop-up, you may have a pop-up blocker installed on your browser. You should get the option to allow pop-ups from PayPal on or near your address bar.
In the pop-up, if you scroll down, there will be a grey button that gives you the option to "Pay with Debit or Credit Card" (which I have highlighted in red below). Click on that.
The screen will ask you to confirm your billing information. It will look like this.
Once you have confirmed your billing information, at the bottom, you will be given the option to create a PayPal account. Click on the bubble next to "No, I don't want an account now" and then click on the "Pay Now" button. I have highlighted both in red below.
You will receive an email confirmation indicating that your payment was successful, as will we, and we will ship your replacement parts shortly thereafter.
Please do not hesitate in sending an email to firstname.lastname@example.org if you have any questions.
Thank you again for choosing Thames & Kosmos. We hope you and your family continue to enjoy our products for many years to come.
