Is there a pattern to Lee Valley free shipping? I wanted to get a PMV-11 blade and chip breaker for my #607, but they are back ordered until 9-21. I thought about waiting until there was another free shipping event. They will be at WIA Cincinnati October 18-20. To drive there is more than shipping but I always see something new from vendors and there are a lot of handtools. I did do a thread search but did not see the data anywhere. Jim
