Im a matrix user, but i also ask alot of questions....that and the fact im registered to uk and usa matrix websites, purely coz i have worked aboard.
You can actually get alot of info on discontinued products online, and your rep should tell you, regardless which supplier it is. Id call up matrix for an up to date price list, the up to date RRP are on club matrix for retail. Apart from that keep an eye on products from previous price list and they tend to have an asterix that products are subjected to regional availability. I asked and i got the excel spreadsheet of what was discontinued. hths xoxo
