LEGO® Bundle Packs
Occassionally some sets are more easily bought in a group to ensure that you can get the entire complete set. This saves the time searching around the internet looking for just the one missing set from your collection. Typically, these would be groups of minifigures or smaller sets in the same series.
Examples of what you find here are the LEGO Friends small animal series or the CLASSIC small brick boxes in various colours.
