Well, doubt the UPS lost the package. You know, 
it is rare on occasion the UPS will loose things. 
My pop sent bill in for 30 years and only once 
did the letter was lost. I've mailed out packages 
for overa year and none have been lost-well one 
person claimed it never came in, and I had 
confirmation-I always do for my protection and 
don't know why they would not offer it? Just hope 
they didn't say that you know. And did ya ask for 
confirmation or anything? I usualy mail all my 
packages that way, and if they live in the US, 
this seller seems fishy. It doesn't take much to 
do these things for your customers and for 
yourself as a seller in case these things happen. 
If your package doesn't come in, leave a nuetral 
feedback on them-with a positive ring so people 
know: Hey, UPS lost package. You know, don't put 
the seller down or diss them, make them look like 
they did a good job, but seems UPS lost it or 
something. So other people in the future know 
this happens in case it happens to them too.
