It is legitimate.....but the Amazon ad is very poorly worded. Another member here bought and did not carry through with the directions and just activated the sim upon receipt. The CCS is more explicit and easier to understand.
There are no special plans. This is a seller who is giving a one-time discount for the first 30 days. The seller is likely given you buyes a $11 discount as a incentive to get the new customer to activate through them, and thus earning a commission.
