What goes wrong
Count the heavy cartons only.
Packaging Wholesale lists Vinyl tape for this line. A week with heavy goods uses a known number of vinyl rolls. The buff rolls carry the rest.
The check before you reorder
Write vinyl, not strong tape, so the pick is the vinyl list.
Keep vinyl in a marked place. Mixed with buff, it gets used first because it feels stronger.
Dispatch on that order
On Packaging Wholesale, put Vinyl tape on the order with the lines it belongs to, so you are not paying a second delivery for the piece you forgot. Free UK delivery starts over £50 ex VAT.
