The whole process is very easy: upload a photo you want to transform in stamp, select the number of stamps you need, introduce the address where the postal stamps will be delivered and then make the payment online.
Some additional details:
- you can order in batches of 32 stamps (so you can not buy less than 32 stamps)
- the price starts at EUR 38.4 for the first batch of 32 stamps valid for Europe (EUR 32 for stamps valid for Luxembourg only), and then decreases if you buy more. Basically, you pay 50 cents more on a personalised stamp then on a normal stamp
- the delivery takes place in approximately 15 working days (but no more than 30 days)
Also, Luxembourg Post offers the service of creating personalised postal cards, at the same web page mentioned on top of this article.
