Then she'll be extra unhappy when you add the price of the Turts themselves!

Remember you'll need a light hood to put the fluoro into, and some gravel and plants and stuff too. Each pretty cheap by itself, but adds up.

You may be able to do better on the tank price if you speak to an aquarium maker or wholesaler, and you could probably do better on the turtle dock through URS or another online supplier. But overall the prices seem pretty good (I have no idea what filters are worth) and there's a lot to be said for convienience if its only a few dollars difference. If you buy all the stuff at the same time from the same place, ask for a discount and they'll probably give you some $$ off or throw in some food or gravel or cheap stuff as a bonus.

Goodluck! (remind your mum that christmas is coming and maybe chuck in an advanced birthday-present suggestion )
