Amex has been sending out targeted emails over the past several days to promote spending at Amazon.com. Depending upon your card and your account, the precise offer terms will vary, but in general the offers that people have been receiving are 1000 points for spending $50 in a single purchase at Amazon.com between March 18 and March 31, 2008.

Examples of some offers that have been reported include:

• Amex Blue: $10 statement credit or 1750 points
• HHonors Amex: 1000 points
• SPG Amex: 1000 Starpoints
• Platinum card: 1500 points
• Gold card: 1000 points
• Green card: 1000 points

Purchases made via PayPal and purchases made at IMDb and ShopBop do not qualify. However, no exclusion seems to be made for gift cards. I spoke to a CSR to specifically ask about this and she agreed that gift cards should be allowed.
