For Swarovski beads a quantity variation of up to 3 % is normal, standard within the trade and to be accepted. Prices are frequently calculated up to 4 decimals, however only 2 decimals are being displayed on the website. This can lead to apparent price differences in the shopping cart especially in case of ceramic beads and Swarovski crystals. For example if a bead costs US$0.0142 the shopping card and the shop will display a price of $0.01, however 1000 beads will cost $14.20. These rounding issues cannot be adressed in a different way due to technical reasons.
