Rosenivy, you made a good choice. Ignore anyone trying to antagonize you for whatever reason. I buy & sell online all the time. Heck I even bought my car online, I aged about 100 years for fear of losing $25,000 but that's another story! lol But just because you can find item xyz for $X doesn't mean the seller is trustworthy enough for you to hand over your cash.
Some on here happily advocate buying, using and returning it as a trial without any regard for the consequences of their actions in the long term.
You did what's right for you and that's what counts. Enjoy your reader. I know you're going to love it.
