Start shopping for next year now. Items such as ornaments, wrapping paper, Christmas cards etc. They are easy to store and cheaper to buy during the after Christmas sales.
Right now is also the best time to buy clearance toys. Stick to the classics as what is in right now, wont necessarily be the hot item next year.
Perfumes/Body washes and health and beauty items typically go on sale right before Mother's day. (Shop clearance after for best prices) and electronics around Father's day.
