Yeah. . . I used to work at JcPenney's and I definitely went a little crazy with my discount. It was a good discount though, 20% off. I paid less than $40 on my prom dress that year (including tailoring).
My boyfriend will keep me in check for the tank though and like you said, I pretty much have all the essentials. Except for some more plants. I'm planning on picking up some Hornwort this weekend. And I'd also like to add either an Anubias nana or a java fern. I think they also had some crypts there, but I couldn't remember what would be appropriate for a 5 gallon. I'd really like a carpet plant, but I didn't see any while I was at PetSmart (probably not a bad thing, since I don't the lighting requirements of any of the carpet plants.
I'd really like to add in more animal life to the tank, but I'm limited with a 5 gal. My lil sis really wants a fish, but I know there's not much I can put in with Pete. (Mom said she couldn't have her own tank right now). I told her she pick out a snail for the tank, but we didn't really see anything that either of us liked. Maybe once I get it planted a bit more, I can look into putting some ghost shrimp in there for her.
