Step 1: Go to your Account tab →click Settings
Step 2: Head to Variation Settings. From here you will be able to change the Price Comparison % and or the Minimum amount. You can do this by deleting Burdi's default setting of 5% and $5 and entering your own threshold.
Now, if the purchase of a product is equal to or more than the threshold set (as shown below) compared to your previous best purchase price then you will be notified of a variance.
Burdi's minimum amount is set to $5 meaning that even though the percentage is 5% we will still only notify you if the total difference is above $5 to avoid unnecessary variation alerts. You can use the Minimum amount before creating Variation option to ignore those few cent differences between the price comparison.
