Yes I'm in the UK and...
I sell handmade button badges, cutting the badges out by hand and using a hand press to complete the badge. I have a very well developed right arm as we sell quite a few of them.
I also make and sell Calendars, Bookmarks, Tote Bags, Caps, Keyrings, Fridge Magnets and sell coins. These items are available as and when I have the stock to sell them so appear and disappear virtually instantly.
Occasionally the products are not available for sale, we are either on holiday or more frequently being overrun with orders, we always despatch on the date Etsy generate from our lead time as all handmade or assembled items are made to order, sometimes we have to temporary close the Etsy shop so that we can make our lead time promise.
I only run the business part time these days. I do not work weekends, my normal hours which are 9am to 4:30pm UK time Monday to Friday, message sent to me out of these times get a reply the next working day. I always have an away message auto reply if I'm not available to chat.
