If you’re looking for a gift for the railway modeller in your life then I may have just the things for you.
Check the Model Railway Products category for transfers and one offs for OO gauge layouts, all of which will be dispatched quickly and in plain wrapping so you can sneak them past the person they’re for.
I also have a lot of products available through 3D printing service Shapeways. Of particular interest to your railway modelling friend or relative will be the OO gauge section of the shop. All prices include VAT and delivery (there may be some differences outside the EU). Shapeways estimate a ten day delivery time for their products, though my most recent order arrived in less than that.
