Long time lurker, first time poster. Please do correct me if I've forgotten anything.
I received an email from Vaja Cases today advising a 20% off discount site-wide. They're a Brazilian manufacturer that does very high-quality leather cases for phones (several models), iPads, Macbooks, and a range of leather accessories such as wallets, small handbags, keyrings, etc. Prices on their phone cases start around US$34 and go as high as US$260, 12" iPads are $129-$240, and Macbooks are $440. Check the site for prices on other items.
Discount only applies to purchase price, but I did test it on items already at sale prices and it still applied. Shipping varies depending on how big and how many items you order, a test order for an iPhone 7 Plus case was US$23. Code will be good to 12 January, but since Brazil is several time zones away I expect it will work through 'til the 13th for us.
Maybe not 'bargain' prices, but you'd be hard-pressed to find anyone who makes leather cases of this quality anywhere else.
They're decent but ridiculously expensive for phone cases…
