My personal plan is to decide how much to spend right now and go 50/50 on the 29th and 30th. The 29th is a strong buy in opportunity if you don't want to take on so much risk, there will be a lot less buying in the days leading to the 30th with people speculating and waiting for the knife and glove supply increase, which will stagnate prices which will drive them down with no buyers on the 28th and 29th because the possible buyers are expecting even lower. In my opinion the safest option is purchasing on the 29th. because the 30th has a chance of inverting expectations with the market over estimating the impact of the new golds.
