How expensive is the living desert gift shops?????

The gift shop is expensive.

I found it to be fairly expensive. But not too out of line with other attractions' gift shops.

Gift shops are usually expensive. Hopefully it's tied into maintaining vthe gardens and animals.

Is cheap i think i paid 25 per person...also try to go early is a nice walk before 12pm

It all depends on what you want to buy.... Some items are very affordable and some are more expensive depending on what you're wanting.
