The core difference is price and eligibility

Side-by-side

At the published annual prices, the discounted plan is $70 less per paid year. At the monthly prices, it is $7.50 less each month. Prices and trials can change, so confirm the plan displayed to your account.

Which plan should an eligible person choose?

If Amazon offers the discounted plan to your account and you want Prime, paying the higher regular price usually has no obvious economic advantage. Compare plan details on the final signup screen in case a specific feature or condition differs.

When regular Prime becomes the real comparison

The regular plan matters when discounted eligibility ends. Before that transition, rerun your value estimate at $139 annually or $14.99 monthly. A membership that easily clears $69 may not clear twice that amount.
