I WANT TO BUY A BATH ROBE SIZE TRIPLE XL.I LIVE IN ISRAEL, SO IT HAS
TO BE THROUGH A SITE THAT SUPPORTS INTERNATIONAL BILLING AND SHIPPING

Genuine Turkish Bathrobe at Hammacher Schlemmer $99.95.  For
international orders, you can order online or there is a special
telephone number: 513-860-3397  They accept Visa, Mastercard, Diners
Club and American Express.

I found references to XXXL bathrobes on some other web sites, but they
all quoted the same price and led back to the Hammacher Schlemmer site

Search strategy on Google: bathrobe, XXXL

Landsend also have quite a nice choice of bathrobes for a bit less
money. They have several colors for women up to 3XL for $82. (Of
course shipping and Duty is extra.) There is a choice of styles and
colors for men, although the men's sizes only go up to 2XL. However,
Landsend's garments run large - I always order a size smaller than
normal.
