Every month, I invest in the canadian couch potato ETF portfolio model (VXC, VCN and VAB). I noticed as of now, everytime I buy VXC and VCN shares that I pay a small commission for each buy...for example the last one I paid 28 shares for VXC at 28.14$/share (795.48$ in total)....however I also noticed I paid 0.10$ of commission...now that number seems small, but if you accumulate that in years, it may add up quite substantially,right???
Should I start piling up my money until I reach 1000$ or an X amount of money and then buy my three ETF's or should I continue what I am doing and invest every month a small amount? The previous month I paid 0.05$ in total for all three VXC VCN and VAB, but that was because I invested less money. So I am confused on wether I should continue what I am doing or change it all up and invest in large amounts instead.
