I got a message from this number with that same offer ($2600.00 free vacation to cancun and a bonus vacation for up to four people to give to a friend as a gift) but not saying it was from walmart.

report any number you may think a scam to phonebusters.com or RCMP.ca for more information

Calling saying that you entered a contest from Walmart and your name has been selected to have a vacation for 4 to Cancun, worth 26 000$..... To accept the trip to press ONE, to pass the offer, press THREE...

They don't tell your name, it's a recoreded message of a woman telling you all those details...
Bad news is... Trip to cancun is not worth 26 000$, on which ever resort you choose it will never come up to that price... and also I DONT SHOP AT WALMART!!!
