I've used Safeway.com under 9.1, can't recall if with IE or Netscape.

For me it was a waste of time - [1] The organization of the site is horrid, quicker to 'Search' for each item by name than to try and locate it within their idea of a heirarchy (none of my Safeway Club Card info was in the system, so I had to add each and every thing I wanted by hand), [2] they don't take coupons and [3] unless you specify NO SUBSTITUTIONS on items you get things like a plastic bowl of diced onions instead of whole onions.

Our delivery guy used to work for WebVan and even he was commenting on how S. had a way to go before it was friendly.

All I can say was thankfully delivery was free after an in-store coupon.
