Sainsbury's mile long receipts

The Sainsbury's shopping experience appears to now be augmented by a receipt that comprises a wealth of add-ons. I welcome the additional opportunity to provide useful information but is it helping me to offer 12p off something if I first spend £40 on something else?  The complexity of offers devalues their proposition and if anything leads to frustration over the concept. With the sophistication now in place to do customer profiling Sainsbury's feel this permits the receipt explosion. Epic customer experience is always driven by simplicity and by understanding what the customer wants, this receipt bundling is missing the point by a long way and needs to be stripped back or stripped out.
