For my birthday (back in August), I decided I really wanted to order a Gobstone Alley box as a present to myself. I got a one-off box for about £35 (the company is in Poland so I bought mine in euros).
If you’re unfamiliar with Gobstone Alley, they sell monthly Harry Potter related subscription boxes, filled with between 11 and 15 random and mysterious goodies (previous items have included a quill, wands, prints, stationery and you get the idea). The boxes also always include one wearable item (usually a t-shirt), some collectible playing cards, a candle from Incendio Candles and some loose leaf tea made by a company called Cosy Elves. The boxes are also filled with goodies from small independent retailers so you really feel like you’re getting something unique that’s been made just for that month’s box!
