I emailed customer service, but this only came with 1 truck, not a set of 4 as the description says.
Yeah, I just saw an email fly around about that. Very sorry. Looks like we goofed.
Yup - same here. Only 1 arrived.

I got an email Monday saying they were aware and working on it. Any updates? I’ve never done a woot return, but I’m wondering if I should get ready to send this back or stick it on my soon-to-be 2 year old’s birthday cake on Sunday. 
I haven’t heard anything yet. You may want to make back-up plans for Sunday. I’m sorry.
Me again. 
Still haven’t had a follow up from CS beyond “we’re working on it.” Any updates? I think I’d just prefer to send it back and get a refund.
Argh, sorry. Let me talk with the CS manager.
Important question:
Do you have a sandbox?
I wrote it. 
You’re welcome.
As it turns out, I have a sand and water table, so this little truck will be put to good use
Cleverly done, as always!
