OK..I do understand completely that when placing a grocery order that some items may not be available when it is 'picked' in the early hours of the morning...BUT....in allowing a substitute one would expect the missing item to be substituted 'like for like'. Thoughtless errors can occur such as a while back - the seeded gluten free bread x6 was substituted with seeded wholewheat bread x6... The vegetarian sausages x8 were substituted with pork sausages x8.... but there have also been some inexplicable and rather odd substitutions over the course of the last 5 years or so.....all of which have been a learning curve as to which items I will not allow substitutes for. Todays delivery had some really well thought about and very appropriate substitutes - Sainsburys frozen salmon fillets x4 were substituted with Youngs frozen salmon fillets x4. (price diff £1) Hubbards peach slices x2 were substituted with Sainsburys peach slices x2. (price diff 98p) Sainsburys nectarine punnet x4 were substituted with Sainsburys nectarine punnet x6 (price diff 50p) Sainsburys cornflakes x2 were substituted with Sainsburys organic cornflakes (price diff 80p) but it is the wine substitutions I am a little puzzled and perplexed by - ordered Sainsburys Sauvignon Blanc x3 - have been substituted by Sainsburys Soave x3 also ordered Sainsburys Chardonnay x3 - have been substituted by Sainsburys Pinot Grigio x3 This is the same as - ordering oranges and being given apples; ordering beef steak and being given pork steak; ordering tea and being given coffee; Just as oranges are not the same as ALL fruit, beef is not the same as ALL meat and tea is not the same as ALL beverages, sauvignon blanc is not the same as ALL wine and likewise chardonnay is not the same as ALL wine. If there were not any of the Sainsburys Sauvignon Blanc available, then substitute it for another brand of Sauvignon Blanc - just as you did with the fish and peaches! Sainsburys please please please give your pickers guidance in this. It saves a lot of hassle and returned goods which you have to refund the exasperated customer for!
