When is the next big sale for lululemon?

As an AI language model, I don't have access to real-time information or the latest company plans. My knowledge is limited to the data available up until my training date, which is April 2022.

For the most up-to-date information regarding upcoming sales and events at lululemon, I recommend visiting their official website or contacting customer service directly. They will have the most accurate and current information regarding upcoming sales and promotions.
