So you want to shop Amazon's biggest sale of the year? As the name suggests, you must be an Amazon Prime member to have access to Prime Day 2018. There are a few different ways to score yourself a Prime membership if you don't already have one.

If you're not trying to pay a single cent and you just want the option to shop if you'd like, then the first thing you'll want to do is follow Thrifter on Twitter. Once we tweet an update about when Prime Day 2018 begins, you can sign up for a free 30-day Amazon Prime membership. Then you'll be all set to shop.

Alternatively, there are a few other ways to snag yourself an Amazon Prime membership. If you purchase yours before May 11th, you can get Amazon Prime for $99 per year. Otherwise, the price will jump up to $119 per year. Don't want to invest that much all at once? You can opt for a monthly Amazon Prime membership that'll cost $12.99 per month. If you have EBT or Medicaid, that price drops a bit as well.

If you don't want to miss out on Amazon Prime Day, you absolutely need a membership, so make sure to get yourself a free 30-day trial (or some other form of membership) if you're interested.

Keep in mind there will be additional sales to shop that won't require an Amazon Prime membership. Walmart, eBay, BuyDig, Kohl's, Best Buy, and more have all held competing sales during Prime Day in the past. Without a Prime membership, you won't be able to score some of the best Lightning Deals of the year, but thanks to these competitor sales, you'll be able to participate at least a little bit.
