The discount is staggered. You get 10% off purchases of 5,000 to 9,500 points, 15% off 10,000 to 14,500, 20% off 15,000 to 19,500 and the full 25% off only when you buy 20,000 to 30,000 points.
At the top end, 30,000 points will cost you $787.50. These can be converted in 35,000 airline miles in the majority of programmes. The price per mile works out at 1.6p, which is certainly not a bargain.
The best deal is to buy 20,000 points for $525 as that converts into 25,000 airline miles and a price of 1.5p per mile.
The rules are straightforward – points post within 24 hours, maximum purchase of 20,000 points per year (increased to 30,000 during this deal), your SPG account must be 14 days old to participate.
This deal has, in the past, been more attractive. However, the strength of the $ against the £ has pushed up the price since this offer last ran. One of the best uses is to stock up on Lufthansa Miles & More miles as these can no longer be bought directly from Lufthansa.
Immaterial of whether you use the points to buy miles, it can still make sense to buy ALL the points you need for a room. The Aloft in Liverpool costs £179 on 21th May. Alternatively, you could buy 3,000 SPG points for just £45 (based on buying 20,000 points). The reward night would also be cancellable, whilst the £179 room I quoted is not.
