BRUSSELS, March 15 (Reuters) - A shop has opened in

Brussels selling still-sealed unwanted Amazon ( AMZN ) parcels

by the kilo, effectively a lottery ticket which could win the

holder a connected watch, a smartphone - or a worthless trinket.

The shop called "Pile ou Face", French for "Heads or Tails",

is located near the central square Place Flagey and offers the

parcels at 16 euros ($17.40) per kilo. Customers pick a box

among the dozens stored in the shop and some open them on the

spot.

"It is like gambling. I paid 40 euros and I got three or

four headphones, I did a good job," said Paul, who declined to

give his last name.

Gisele Peeters is a bit disappointed, though. Her 14.40 euro

parcel contained an old-style telephone with a dial. "It's not

something I would have bought. I'll try to resell it," she said.

Arnaud Userstam, who founded the shop, said connected

watches and smartphones are the items people are happiest to

get, but others return home with clothes, or sometimes

especially weird items.

"A lady got 100 toothbrushes for dogs," he said.

Userstam started the business after he and his wife wondered

what happened with parcels with delivery problems after

experiencing the issue themselves. They found out other similar

shops existed elsewhere.

Pile ou Face signed contracts with the giant U.S. e-retailer

Amazon ( AMZN ) in Europe to get parcels that were not retrieved from

pickup places, that were returned by customers or simply got

lost.

Userstam did not elaborate on the contracts, though he said

that previously these parcels were just destroyed.
