I got the yellow card in the mail too. I know there are people out there that get scared when they see signs like this one. My advise is always don't just look at the mail and react!. Read it twice and do a search on it if you are not sure. Also the first place to look for a company info is the Better Business Bureau. I did that with this company and they install water systems for house that don't have city water. This company had 45 complains in the last 3 years. They try to get you with a free water test at home. The way they advertise is deceiving, especially older people. Also, check for phone numbers that are registered as scam or telemarketers.
Got the same post card. It is definitely a scam, since there was extremely little information on who it is from. I might have been contacted by phone from these scammers, but I block all phone numbers I don't recognize.
Follow up this is Mail Fraud, plain and simple. They want to sell you water softeners and filters. The other dead give away
was it was addressed to my Son and current Resident.
Also got the same postcard described in earlier posts. Googled AWP and according to the website, they sell water purification products and services. Strangely, the phone number on the card (302-544-7145) is not the phone number on the website. Also, and this is really strange, the address is next door to a place of worship my wife and I have been to a few times. Hmmmmm
