I LOVE tegu blocks, well Monster does also!!
We recently got him another set through Fab.
And now, they're at SneakPeeq.
Unfortunatley, I don't have any discounts to offer you BUT...
if you Peeq around you can find different badges for certain amounts off the total price, which is just as good.
This is one that I had and used already, but there are several badges hanging around...you have to peeq to find them!!
