There can be varying levels of "shopped" too by my understanding . Shopped can be everything mentioned above ie. full strip,clean,re-bulb,re-rubber, new legs , coin mechs fitted etc.  or it can be a simple clean,re-rubber, and re-globe . Obviously what you pay to have your pin shopped will vary depending on the work done but it all comes down to how much you want done to it before you get it and how much you want to do yourself .
