This was in my cart for a while and it's always $12.75 which is still not bad. But I purchased a bin of duplo size blocks from Mattel (no wagon) and it was about the same price. After 10+ days though, Mattel finally told me they don't have that in stock?! So all of sudden these became $7.59. Yes it's add-on but I have other stuff to buy anyways.
$7.59 with 54 duplo size blocks in unique colors with a wagon seems great. Plus reviews are great!
***REMARK: For those who think they have many "fake" vine reviews, ok maybe yes but I see some reviews aren't from Vine and are great too. Also I judge from the brand. It's Battat and it makes a lot of toys for young toddlers. So if you're getting these for young toddlers who aren't serious builders I think it's fine. I won't compare it with REAL lego duplos but I think it's probably along the line with Mega Bloks. My 19month old and almost 5 love mega bloks so I think they'd love this too. The little wagon is a plus for added fun and more storage space. Thiis is just my 2 cents.
