I saw these at Costco last week but did not know if it was a bargain or not (been a while since I shopped for this) They had heaps in stock. Just noticed a previous OP link to the Loaded Trolley blog that has the info - refer the link.
I have used one before and they are great for 1-3 year old kids. Though, I think they work better on longer bikes rather that shorter mountain bikes due to knee clearance. Was too tight previously to spend over $200, but at this price may grab one myself. I don't remember them ever being this cheap!
For non Costco members, it is $60 joining fee, but cancel anytime in the 12 months and get 100% of the fee back.
A lot cheaper than the previous deal on OzB…

Oh, I should add, this is the deluxe version not the standard version!
I have a WeeRide seat which I bought in 2010, for $89 in Canada.
These seats a really good. My daughter is now four and a half, she still rides with me.
I feel very safe as she is in-between my arms. She has has a great view, and a padded arm rest to rest on.
Looks like the Australian RRP for this product is really high.
