No. I said "on sale" USUALLY might mean at a reduced price. Not always. In these instances, it just means that the tickets or the car will be available next month or on a certain date, or at a certain place. In these instances, "for sale" and "on sale" are synonymous.
It can be confusing, I know.
1. Tickets are on sale from the booking office.
(Does it mean that we can get the tickets at a reduced price?)
2. The new model goes on sale next month.
(Does this sentence mean that the new model will be sold at a reduced price next monthe?)

The meaning must be derived from the context. For example, I cannot yet buy tickets for a hit musical that will play next fall. Season ticket holders may buy season tickets for several plays now, but individual seats will not go "on sale" until a later date. But an advertisement in today's newspaper says: "Cole Hardware Hardware Hot Deals: Sale Prices Valid Through April 30, 2016"
The tickets will not be at reduced price. The items listed in the advertisement are at "sale" or reduced prices.
The tickets will not be at reduced price. The items listed in the advertisement are at "sale" or reduced prices.
