Met-Rx meal replacements?

[left-of-center2012]

About 20 years ago I lost about 50 pounds by using Met-Rx once a day as a meal replacement.
(It's a flavored powder which you make into a shake)
I liked it because it uses Sucralose as a sweetener instead of the sugar alcohols, which give me intestinal grief.

I'm thinking of trying it again.
Does anyone here use it, or tried it lately?

I see the prices online are now $32 and up for a box of 18 envelopes, plus shipping.
It isn't available near me.

Any suggestions on who/where I can find it cheaper, as I am now retired on social Security.
Thanks
