Great question.Nice post. Thanks. How do you typically find the clearance sales?
In this section of BITOG " Product Rebates, Sales and Promotions". Recommendation is to subscribe to this section of BITOG, and you will receive notification of sales, clearances, etc.
On a not so happy note, pre COVID many of the major "big box" auto parts retailers would regularly drop an oil product line at the end of year OOA December and replace with a different product line the beginning of January. Post COVID, this practice rarely occurred. The one exception post COVID has been Tractor Supply, which seems to continue the practice of removing one producer of motor oil for another producer.
Being a member of BITOG has saved me thousands of dollars in motor oil, and more importantly, I always have oil ready to use in my garage, so I don't have to run to the store, and find the oil I want out of stock, or at a crazy high price.
It is work to get the clearance items. Mapping out all the stores, having a plan to make efficient and timely visits before the clearance items are sold out, and finally looking around for clearance inventory in the wrong spot, so when one is "last to the store", still finding the clearance oil, after the easy to find clearance oil was already sold.
