  1. hello

    This is my third time trying to connect with you. Last week I was chatting on line about order number 9709630 that I am trying to return ( treadmill – Ironman) and was promised that someone will call to set a date for pick up. Can some PLEASE help

  2. Extremely very very poor service buy phone holding and customer did not getting answer. Why they are holding line more than 50 minuets still they are holding lines. Also they are sending wrong address package.

  3. Will you still be selling the Kirkland men’s wool pants in size 44×32? I have been buying them for years and they now don’t sell that size in stores and they have been sold out for months online.
