Nobody is telling you how to get the guns you want for cheap because of three main reasons. We don't know how, we don't want to, or it's impossible.
Most of us fall in the first category. We want cheap guns but we don't know how, so we don't.
If there are people who know how, they're not going to tell you because they don't trust you, can't be bothered to take the time to tell you, or want to keep a monopoly and make profit.
Or maybe it's just plain impossible in Canada. You do know that non-functioning items that look like real firearms are illegal in Canada right?
Yea, so nobody can help you so stop asking. If you must ask, ask a retailer, but I'd doubt they help you.
