Shelf price range checked · details
We track 49 rated envelopes & mailing products, and the middle of that pack scores 4.6 out of 5. This one is on 4.7. Top quarter of the shelf. In an aisle where nearly everything rates well, the distance above the middle is the part worth reading, and this one has it.
2,204 people rated it, where the shelf median is 2,495. Enough reviews to trust the direction, not enough to close the question.
The shelf runs from £1.20 to £29.99 and the midpoint is about £7.99. On price, this one is in the bottom third. Cheaper than most while rating above the middle of the shelf is the combination we look for, and it is the strongest thing this one has going for it.
