I second everyone's ideas! ^^'
But my personal ideas would be:
More flytraps! I mean, it's called the flytrapshop afterall
On the verge of sounding selfish, Gold Strike would be a sweet addition.
More Sarracenia, Sundews, and Butterworts!!!
Good priced Cephs and Helis would also be so appreciated.
And don't forget the grand Cobra Lily! Preferably the Mountain variety.
I also agree on the fertilizers, pesticides, etc bit.
Oh, oh! Trays, Humidity Domes, and budget-friendly Mini-Greenhouses!!!!
Larger volumes of media for a slightly discounted price (as compared to say, buying 8 1-gallon bags)
And for the site itself, I think it'd be much more neater/cleaner/user-friendly to have one block for a particular plant with the option to buy it either bare root or potted, instead of having separate listings for the plant potted and bareroot. I do have a particular site in mind that already does this and I'd like to show it, but I don't want to break any rules.
I am done
