Regular Welcome Offer:

Earn 25,000 bonus Starpoints® after you use your new Card to make $3,000 in purchases within the first 3 months.

Limited Time Bonus Offer:

Earn an extra 10,000 bonus Starpoints® after you make an additional $2,000 in purchases within the first 6 months. This additional offer ends 4/5.

That is 35,000 Starwood points, or 105,000 Marriott points for $5,000. (Before the regular value of your spending). Looks like an even better return on your spend.

The 100,000 points offer is supposedly only for a limited time.
