Used this service through another vendor many times. Didn't matter what you purchased. Add item to cart, proceed to checkout, click sizzle an make a profile with your CC. Total gets broken down into 4 payments due on the date of purchase. So you buy on a Wednesday payments will come out on Wednesdays. Nice thing isnyou get to change your dates once with no Fee. Also you can always pay ahead of Scheduled date with no penalties. It's way easier to get the app an setup your profile before hand. Saves time an the headache of setup while trying to make a purchase. Had it happen the 1st time I tried to setup the profile in the middle of a purchase only to get to the end an the item Sold out on me. All in all its a great service and I use it frequently.
