This is not normally an error.

Products priced less than £1 or so may not be awarded points for a number of reasons.

Other products are unpriced - such as mobile phone contracts - which we receive a flat rate commission for. Don't panic, examine the retailer profile for more details of the points you should be entitled to.

As for low value purchases, we will award points if we can track you purchase as they are typically bought in larger multiples. (You will get X points per pound spent, rather than an absolute value.)
