Edit by Ivan 2016-12-07: Circle is out of business, so this guide does not work any more. Please stay tuned, we are working on a new guide. Thank you. Circle changes to Spark blockchain. On December 6th, 2016, Circle announced that they will no longer be involved with buying and selling bitcoin. Read about it here. If you'd like to try out bitcoin for your new AnyDVD HD license purchase, then I can recommend Circle for a reasonably pain free experience. Circle is based in Boston, MA. and has some major backing including Goldman and Barclays. I was able to set up an account with minimal information and no ID verification with a $300 limit/week. In some cases an ID verification may be required, see here for details. You can link a credit card, debit card or bank account. Debit Cards and Bank Accounts don't have any fees but credit card use is considered a cash advance so fees apply. I linked a debit card. Complete the create a new account sign-up, email verification and 2 factor cellphone authentication setup first. Link your preferred funding method. The key to using Circle for a single purchase like this, using bitcoin, is to set the account to deal in bitcoin not dollars. To do this, (after logging in) click your login name at the top right and select settings. Select currency on the left then click the radio box next to bitcoin and accept the conditions/warning (i.e., market risk) and convert to bitcoin. Since I had a zero balance anyway, no big deal. If you already use Google Authy for 2-factor authentication, you can enable that in the settings area under Security at this time also. Next, off to www.redfox.bz/purchase.html in a new tab on your browser is easiest. Follow through the steps to make your purchase, when it comes to your personal information, it's up to you. I used a valid email address so I'll get the update notifications but I just made up the rest. Be sure to select bitcoin and continue. You'll get a review page, accept the terms and then place your order. Next, you'll see a page with a QR code, the payment address and the bitcoin total due. Now back to Circle (select it's tab or open a new tab or browser instance). If you're not on the account page, click Account on the menu bar at the top of the page. Since you changed to bitcoin as the currency default you should see a Buy bitcoin button and click it. I used copy and paste to copy the information from Redfox back to Circle. Purchase the exact amount of bitcoin from the redfox Order Pending page. There is no fee for making the purchase, however the exchange rate was a bit high at $584.16/bitcoin. I purchased 0.15405173 BTC for exactly $90 US (compared to $99.20 purchasing with a credit card from Redfox directly). Finally, you have to send the payment to Redfox, click Send Money on the menu at the top. Fill in the address and bitcoin amount from the Redfox Order Pending page. Continue to 2 factor verification to complete sending. Head back to the Redfox Order Pending Payment page and hit the refresh button to reload the page. You should see a order completed and order number and a link to download your license key. You can actually skip the separate purchase step above and use your payment option to purchase and send the bitcoin in one step from the Send Money page but I included the purchase step for better clarity. In fact, with one more step we can make things really easy, go back in to your settings on Circle, click on Advanced on the left and under Bitcoin Payment URLs, click the button Enable Link Handler. With this enabled, you can simply click the QR code on the order pending payment page and you'll be taken to Circle with everything (the payment address and amount) filled in for you including the order number in the comments. You may want to right click the QR code and select the option Open in new tab or Open link in new tab so that you can return to the Redfox order pending payment page after you send your payment and download your new license right away without waiting for an email. I spent several hours checking out numerous other wallets and exchanges looking for something simple and Circle was it. Plus I saved a few dollars. Hopefully, relating my experience will make it easier for others to give it a try. After thoughts: Funny, but after looking at some of the issues others are having with using credit cards for their purchase, I actually feel like paying with bitcoin was more secure. You see my credit information is only with Circle which is in the USA. There are no issues with asian credit card processors, fraud alerts or the like. Feels like a big plus.
