Enjoying talking to and meeting people, are important for this position, which is unpaid.
"We are not a retail shop. No one gets paid."
Lancaster spends most days in the shop as does her husband Scott who is the custodian. Both have been involved with the Red Cross Op-Shop for five and four years respectively.
"Most of our volunteers love being here and give up only reluctantly."
New volunteers get thorough instruction and are also working together with at least one other, experienced, volunteer.
"Every shift has two people."
The job involves keeping the stock organised, talking to customers, taking money, giving change. Experience in retail is not required, but it helps if you are a people-person who can make people feel at ease. A willingness to discover what the shop has available, so you can direct customers to the right place, would be beneficial.
There is also a storeroom, from which stock gets replenished and that stock needs pricing, something that is not too onerous, said Lancaster.
"You just look at prices of similar items on the shelf."
Penny herself is in every Wednesday and is on call. Husband Scott is around a lot too. The team has 12 volunteers, who between them fill most slots.
If you would like to know more, pop into the shop, Tuesday, Wednesday or Thursday between 9am and 2pm or ring Penny at 021 103 2534
