Learn me on wash sale rules

So reading up on this, it seems like you can avoid it completely as long as you wait 30 days after selling a stock to buy back into the same one again. Is it that cut and dry or are there any other qualifiers I need to look out for?

A loss on sale is disallowed for federal income tax purposes if, within the 61-day period beginning 30 days before the date of the loss sale and ending 30 days after that date, you buy substantially identical securities. The loss sale and the offsetting purchase of substantially identical securities within the 61-day period are deemed an economic "wash." Therefore, you're not entitled to the loss deduction--and the resulting tax savings--that would ordinarily result from the loss sale.
