There's tons of electronic stuff on clearance at my local Walmart. Some stuff marked as $10/$5/etc actually rung up as $1.
Got 64GB PNY flash drive for $1 (sticker price was 10x higher)
White ONN HDMI cable for $1 (black variant rung up as $6)
There are ONN earbuds for $1
Lots of other stuff, like 4K gold plated HDMI cables and card readers for $3
Tried to find some of these on brickseek but haven't been able to.
This one was $11 at my store but I didn't get it
Link below is another item I purchased in store for $7
