Looking for a new computer? Amazon is jumping the gun on Prime Day with deep discounts on highly-rated portables from top brands. Now is the best time this summer to make that upgrade.

Not already a member? You can quickly sign up for Amazon Prime for $14.99 per month or $139 annually (taxes not included). Keep in mind that Amazon offers a 30-day trial of its Prime membership program, which is an ideal way to cash in on big savings without having to make as big of a commitment.

It seems unfair that, while some of Amazon's very best deals of the year are available during its annual Prime Day sales event, access to Prime Day deals requires paying $139 for a year's membership.
