If you mean the same kind of stickers that we sell here (Holland), we have them in overflow. They are sold by the sheet and in packs too with various themes. I'll see if I can find a web shop that sells them internationally. By the sheet you can get them as cheap as 50 cents a sheet. Some shops sell em in packs of like 3 or 5 for discounted prices. They have just text, corners, borders, figures in all sorts of themes like christmas, easter, baby, wedding and lots more.
They mostly come in silver, gold, black n white.
I'll have a look tomorow to see if I can find a good decent online shop for them.
