Well, our club "shop" has been up and running for five months.
Our monthly turnover of routine stock exceeds £100- selling at cost price, or lower. Shrink tube , silicone wire, nuts & bolts, XT60s etc are bulk buys, so there is no charge for small quantities.
Since Temu and Aliexpress now treat us as wholesalers we get faster free delivery and better discounts, which allows us to extend our offer to include buying specific items to order for club members - radio sets, particuler motors etc Order one Sunday, collect next the Sunday.
We know there are specialist U.K. retailers who make their own unique, wide range of "model boat" fittings etc and sell them online; our club members buy from them, but often the cost of an item is doubled by P&P. Starting with just one well known U.K. supplier, but without his knowledge, we now stock most of his range. We have paid the proper retail price and benefitted from the much lower P&P of bulk purchasing. The items are sold to members at the retailer's list price as a service to club members, we recognise this is a low turnover project of an extensive (expensive) stock. It may be extended, or abandoned according to sales over time.
It is early days, but members strongly support the project and is yet another way to attract new members.
