But that might be changing with the recent Big Spring Sale from Amazon, in its second year. Target has decided to compete for your money as well with a Circle Week event, coming later this month. What is Target's Circle Week?Circle Week is Targets name for its biggest sale, which used to happen once a year but, much to the dismay of Target workers, now happens multiple times a year. Usually, youll see one when other major retailers have big sale events as well like Christmas or October Prime Day.When is Circle Week?This upcoming Circle Week will be from March 23 to March 29. Do you need to be a member to shop for Target Circle Week?Unlike Amazon's Big Spring Sale, you will need to be a Circle member to take part in the sale, but unlike being a Prime Member, membership is free. You can sign up on the Target app or Target.com.What deals can I find during Target Circle Week?Mainly spring items, but sale categories broadly include apparel, patio furniture, home essentials, beauty products, grocery items, toys, books, movies, and music. You can shop in person or online, and there will be a "Deal of the Day" for every day of the event. If you want early access to the deals, you can join Target Circle 360, which starts at $10.99 per month.Here is a bit more detail from Target's press release:30% off tees, tanks, shorts and dresses for the family30% off patio furniture and accessories25% off select Pillowfort, teen bedding and decor25% off Threshold and Casaluna bedding20% off Brightroom plastic storage bins and closet organizationUp to 40% off kitchen and floorcare essentials including Instant Pot, Ninja and Shark appliancesUp to 30% off select LEGOSave up to $200 on select Apple devicesDoes the competition also offer sales?Amazons Big Spring Sale will be taking place from Wednesday, March 20 through Monday, March 25.
