Toys R Us offers 12" Star Trek Sulu and Pike as Toys R Us exclusives. Eek! There, I screamed for you. Sulu and Pike are sold individually as are the other 12" Playmates Star Trek characters. Price is $29.99 each and you can get them online. Here are the links for Sulu and for Pike.
For those local (Philly or surrounding suburbs), I saw these figures at the Toys R Us on Aramingo Avenue. They might be at a Toys R Us near you. It's harder to take a photo at Toys R Us - I was denied the privilege at another TRU; I confess I just snapped them at this one without asking - so the following photos could have been better.
