I got an email today from Tripped Travel Gear. They currently have a special 40% off sale on their website. They usually sell through Amazon and this sale is not valid on Amazon. They have several different sets of packing cubes (with some being compression), as well as a packable backpack and a toiletry bag set. Some of the patterns on the packing/compression cubes are really cute, especially the "National Parks" and "Bucket List" version. I am so tempted to get a set, but I looked through all of the packing cubes (both regular and compression) that my husband and I already have, and really can't justify the purchase. This brand was started by a husband and wife YouTuber couple and has very good ratings and reviews.
The promotion code is "Friendsandfamily". https://trippedtravelgear.com/
