For Christmas a few years back my wife bought me a thermometer from LLBean "First Watch Weather Station". This November 2014 it started to get temperamental, so I called LLBean for suggestions to see if I could reboot it or something. Being age 68 I don't know everything anymore. We went through different motions without success.
I was told it was "100% Satisfaction Guaranteed since 1912" and if I gave them my credit card info they would send me a new one, when I returned the broken weather station I would get a refund of the purchase price. So I got the new one, sent back the old one and never received any refund or email that they received it.
I called them after 2 weeks and they said I would get a refund that day. I did partially get it. My wife paid $19.95, the price when up and I paid $39.95 "Item: TA*******". They discounted what my wife paid to $14.95 (they wouldn't tell me why but maybe my wife got a $10.00 gift card for buying items before Christmas). Wife says no.
I wrote a review on the LLBean web site and after 2 days it was deleted.
If I was told by LLBean up front that I would only get a partial credit and I was actually buying a new weather station I would be OK, If I decided to buy another, but I was never told.
