YEP, that's right!
When I closed a sale on eBay (in my Spectrenoir - Boutique see at top of my Home Page), a French Large Ceramic Antique Cross with Barbotine Roses which measured itself 16 x 10 x 4 inches or 40.6 x 25.4 x 10 cm.
Husband Pieter who is an EXPERT PACKER, had already double boxed this delicate piece.
The measurements of the outer box were: 18 x 13 x 14 inches and the weight was 4 lb or 45.7 x 33 x 35.6 cm and 1.8 kg.
I had NO choice but to select their USPS Priority Mail Flat Rate Envelope
Max weight 70 lbs or 31.7 kg
USPS supplied envelope 12.5" x 9.5"
Just to get out of this ridiculous 'no-choice' thing, I switched to UPS service.
That of course was normal, according to size and weight.
Got my QR code on my iPhone and drove the 42 miles to the nearest UPS Store.
It got delivered timely and in perfect condition, got a positive feedback; customer very pleased!
But WHO in his/her right mind can compose such a shipping selection?!
TIMES HAVE CHANGED...
The same applies to required Length and Width for a ROUND box...
Keep getting such messages, for adding item specifics.
BRILLIANT CONCEPT; DON'T YOU AGREE?
