Labor day weekend

[ezdays]

I did place an order at Trainworld yesterday but did not get an email with the DHL tracking number. I did ask them to cancel my order if they did not ship on Friday because Tuesday will be to late for me. Last chance to ship and mail tracking info would be today.

Trainworld did not respond so far.
Might be they are closed on labor day weekend on Saturday (and Monday of course)?

It's going to depend on how you told them to ship it. This is a holiday weekend, and unless you ordered them to ship "next day" and with "weekend or holiday delivery", there's no way you'll be seeing it before Tuesday anyway. I'm not even sure that DHL does that, I know that the USPS does it for a good price.
