How can I left join price to orders on the right date.
The result should join to orders table the row from price table
where the date of the order is grater or equal to date on price, but not greater then the next row (if exists)
for example

Example
+-----------+-------+--------+------------------+----------+----+-----+--------+----+-----+------+-------+--------------+
| orders.id | email | status | order.date       | price.id | wd | bts | family | r  | tlv | kids | user  | price.date       |
+-----------+-------+--------+------------------+----------+----+-----+--------+----+-----+------+-------+--------------+
|  1        |       |      0 | 1425894699       |  1       |  0 |   0 |      0 | 75 | 65  | 50   | int   | 1425894693   |
|  2        |       |      0 | 1438790336       |  11      |  0 |   0 |      0 | 75 | 65  | 50   | zack  | 1438790326   |
|  5        |       |      0 | 1438790478       |  12      |  0 |   0 |      0 | 75 | 65  | 50   | zack  | 1438790468   |
+-----------+-------+--------+------------------+----------+----+-----+--------+----+-----+------+-------+--------------+
There is a mismatch between the data and results in your question but I think you need a query like this. It's not going to be very efficient if the orders table is big:

SELECT 
    o.*,            -- pick the columns you want
    p.*             -- in the result 
FROM orders AS o
  LEFT JOIN price AS p
    ON p.date =
       ( SELECT pi.date
         FROM price AS pi
         WHERE pi.date &lt;= o.date
         ORDER BY pi.date DESC
         LIMIT 1
       ) ;


Tested (with modified data in the orders table) in: SQLfiddle.
