Most of what a new blog costs goes to three things: hosting, a domain and a few plugins. Black Friday deals for bloggers cut all three at the same time, so this is a good moment to start or upgrade a blog.
The catch sits in the fine print. A $2.49 hosting plan looks like a gift until the renewal invoice arrives, because most hosting discounts cover only the first term and a few cover only the first 2 months. Pick the wrong term and the saving disappears in year two.
My advice is simple. I'd buy hosting and a domain this month only if you plan to publish within the next few weeks, and I'd take the longest term you would happily stay on. Hostinger is the one I'd check first this year, because its Black Friday plans include a .com domain for $0.01 in the first year, which takes one more bill off a new blog.
