Yes, exactly! If you're using ModXL you will see in checkout the 35% discount is automatically applied via a coupon code when you select Bitcoin/Crypto, giving you the total. This also means you cannot use it together with other coupons.

However, you can combine coupons using BuyModa, use our 10% off code "pira10", then pay with Bitcoin for another 35% off, giving close to 50% off total, crazy value when you think about it given it's not even a sale on!

The best way to know exactly how much you need is simply do a test checkout first, select Bitcoin, and it will tell you the total, then that is how much you will need to go buy. Pro tip: add a little extra to accommodate for the constantly changing up and down value of Bitcoin. You don't want to buy, have Bitcoin go down, then you don't have enough to cover the order because you are short 45 cents or something, so add a couple extra bucks worth.
