You know you've reached a new level of tightwaddery when you only shop for secondhand items on sale. Seriously, stores have gone so retail, with prices so ridiculous, it only makes sense to plan your trips around sale days. Here is the information I have for local thrift shopping. Hope it is useful to someone!
Monday: Probably the worst thrift day of the week. Stores clear out the old and clean up the aisles after busy weekend traffic. Goodwill does offer 10 clearance items for $5, but they're so picked over, you're better off using this deal at the salvage store. There you have a greater selection of final-clearance from stores all over the region.
Tuesday: Opening day for This and That Thrift, a small store that benefits St. Luke's Community Center. Since volunteers spend Mondays pricing new items, there will be a huge line at 10 am. Beware the professional antique dealers and Ebayers, who will snatch items out from under you. Glance at the white board behind the counter to see if anything in particular is on sale.
Wednesday: My personal day for thrift shopping. Salvation Army stores have 1/2 price on ALL clothing each Wednesday, even the racks of new things. Otherwise, they have one color tag on sale all week long.
Also, don't miss Goodwill. There is one color tag on sale each week, and clothing with that color drops to 99-cents on Wednesdays. They repeat this deal on Sunday, but why not go Wednesday when the selection is fresher and greater? Tip: Not all sale merchandise has been gathered in the center aisle yet. Flip through the regular racks for 99 cent tags, too.
Thursday: Thriftsmart stores have Thursday donation days--with a bag of donated items, you get 50% off one item. This is how I bought my stove half-price. Thriftsmart is experimenting with a sale calendar like Goodwill, so grab one at the entrance for more daily specials.
Friday: Yard sale if the weather is good. If not, Fridays are a good day for all-purpose thrifting. Most stores put out lots of inventory for the upcoming weekend.
Saturday: I generally avoid thrift stores on the weekend, unless I'm entertaining my mom.
Sunday: I think this is the best day to shop Southern Thrift, because you have more opportunities to save. There are FOUR color tags half-price--the two colors from the previous week, and the two colors for the upcoming week. Since Southern Thrift is more commercial than other thrifts, they seem to keep employees putting out new items on the weekends, too.
I'm not up on all the deals at every store, so if you have more advice to share about thrift store sale days, add them in the comments!
