NOW() BETWEEN sale_start AND sale_end
is equivalent to
sale_start <= NOW() AND sale_end >= NOW()
NOT(A AND B) is equivalent to (NOT A OR NOT B), so "NOW() NOT BETWEEN
..." is equivalent to "sale_start > NOW() OR sale_end < NOW()". Can
sale_start be greater than NOW() in your data? If not, we can simplify to
SELECT prod_name, sale_price, sale_schedule_status
FROM products
WHERE sale_end < NOW()
AND sale_schedule_status = 'active';
Can sale_end be >= NOW()?

Are you sure? ;)
Let's see..
NOW() NOT BETWEEN sale_start AND sale_end =>
(There was a 'NOT' before BETWEEN in orginal post)
=> NOT ( NOW() > sale_start AND NOW() < sale_end ) =>
=> NOT (NOW() > sale_start) OR NOT ( NOW() < sale_end) =>
=> NOW() <= sale_start OR NOW() >= sale_end
