you can buy extra subscriptions into the future....or you could look around for some promising young artists who may not be subscribed...and choose one/several to buy for....
you could buy some masterskins....a percentage goes to WC of the non Stardock ones....or buy SD ones...
sometimes people need help with OD renewals....
if you wanted to make it a bit of fun...you could have a little mini competition....best wall...or 25 words or less...why you want a subscription etc.
lots of ways....
just a suggestion....
or I'm sure someone will be along to tell you how you can do it directly....
Edit...too slow..
