I did the Gold Wprkshop during my first three months of shopping. The most useful things that I learned came from the give-and-take during workshops woth schedulers and veteran shoppers, woth lots of audience participation. Since this aspect is lacking in the DVD format, I favor the workshops at the IMSC conferences.
Full disclosure: for the first time, I will be leading a workshop at an IMSC conference in a few days. That is my way of paying it forward for all of the help and mentoring that has been given to me on two shopper forums, by other shoppers, and by MSC staff and schedulers over 6 years.
Whatever you do to improve your shopping skills and learn about innovations and technology will boost your shopper income/effciency. People learn in different ways. So, read, read, read, on the most active shopper furums. But, also consider forums where you can see, hear and hug your fellow shoppers. This can be a very lonely enterprise without interactions with real people (That includes forum friends!) who have walked the same road.
And, at these gas prices, we may all be walking, lol.
