Sandy, it is not for USA. I asked my old customer from USA to check it and he can see message and space for codes.
Maybe you clicked to hotel that doesn't support those kind of codes.
Your customer sees the HOTELS.COM CODE BOX NOT THE TESCO CODE BOX. THEY WERE 2 SEPARATE PLACES TO ENTER CODES yesterday.
You are also WRONG because I successfully booked a $500/night hotel at Walt Disney in the US 2 nights ago FROM here inside the USA. Like I said before it is entirely possible they have since changed that and it no longer works from INSIDE USA to a USA Hotel. At that time it did.
I bought a 2nd coupon for a 3 nite stay elsewhere in the USA which LAST NIGHT worked in 5 different hotels that listed TESCO COUPON and still show them accepted located in another state here in the US. At that time There was a SPECIAL BOX FOR TESCO CODES. I didn't actually complete the reservation but I did APPLY THE CODE and it worked fine and gave me the proper credit at each place (you apply the codes BEFORE payment). When I cancel the unbooked reservation the code was restored.
TODAY when I went back to the 5 hotels that took the coupon yesterday the TESCO COUPON BOX did not show just as in the screen prints above by your fellow seller, only the "regular" hotels.com/uk coupon box was available. The TESCO SPECIFIC BOX no longer is there. Again, this is for USA hotel with USA purchase. Don't know about outside US. However your buddies screen prints DO NOT show the TESCO box either
The reservation in the screen print below is a $525 USD/night hotel so quite obviously the coupon worked 2 days ago booking from IN THE US to a US hotel.
I think the reason everyone is saying their codes don't work now is because they are entering them in the HOTELS.CO/UK coupon box and not the non-existent TESCO SPECIFIC BOX which is no longer there.And you can see I was charged for it (with a foreign transaction fee).
