The first tip that this is a scam is look at Canada Post Stamp - Postage Paid: Addressed Admail. Putting a red sticker on your mail box and Canada Post will stop putting or delivering Admail.
This is Direct Furniture Warehouse. They are just trying to get your personal info so you can attend their open house. Once you refuse to give them your info, they hang up on you. So rude!!!
I just got a card that looks like a Canada Post missed delivery card saying I have a parcel for an Android 7" tablet......
I did not order such a thing.
I just received a "Notice to Call" postcard in the snail mail with a "Status" of "Ready to Claim" an Android 7" Web Tablet with Camera + WIFI. Other bait included "Call our Distribution Center now" and "We can hold this package for only 72 hours." Tiny barely-readable fine print said I'd have to sit through a 90 minute presentation in a room with the fire exits locked from the outside before I could claim my "free" tablet.
Sadly 73 hours had passed so I didn't bother calling their phone #.
