Merinoandco.com.au is doing a sale at the moment, their 100% Merino T-shirts on sale for $20 each.
Merino fabrics are highly regarded because its a natural fibre and its anti-bacterial, breathable, sweat wicking (hence you don't have to wash it as often as say cotton fabrics). They are great for travelling or just everyday use. I own a Navy crew T-shirt for 6 months now and loving it, I paid $69 previously :(
If you are a new registered customer you can use the WELCOMEMERINO for $20 off for order over $50.
I bought 3 crew T-shirts for $40 shipped super happy!
