They had a 25% off sale not that long ago
@Clareew so it probably means they won't be on sale for a while yet. Interesting that it was only 25% off and not the usual 50%. Also the current Vogue sale is only 40% off. Patterns seem to be getting more expensive in the UK. The pound dropping against the dollar will probably have something to do with it.
The UK Simplicity website does a pattern of the week for £2.95. It's worth keeping an eye on in case a pattern on your list turns up.
