I have anubias bonsai (very similar to nana petite, actually hard to tell the difference unless you know how) $12 for a good clump (around 20ish leaves)
I also have Crypt wendtii green, but they are pretty tall, like 8 inches.. $10 for 3.
Also have subwassertang for $6/golfball
Creeping moss for $8/golfball
DHG belem (the shortest type) $10 2x2 patch
Monte carlo (good carpet, for low medium light) - $10 2x2
also have a giant pot of microsword for $20, will be enough to carpet your whole 2.5 gallon and a 10 gallon if you know how to plant it.
shipping is $6-7 for a regular box, $10 for a insulated box
And yes you can get a very decent light with a cfl.
Great way to DIY is to go to a lowes, buy a clip work light (domed) $7 + a 13w 6500k daylight cfl ($9 for 2). This will give you high light if you keep it close, medium if you hang it high.
Also selling rare Crypt Dewitii $50 each lol =D
