Hi, sorry for the confusion. If you look closely, the sale is offering different discounts for longer amounts of time, as shown below.
For 24 months, the $.89 hosting plan will cost $83.76. I know this may make you want to choose a smaller plan, but let me warn you that if you choose a smaller plan at first, it will renew at the regular price (which means that if you’re looking to get the cheapest hosting now, I’d go with the 2 year plan while its still on sale).
Of course, if after purchasing, you’re not satisfied with the hosting, you can contact support and they will refund the purchase within 30 days.
