My only conclusion to the very cheap price is that they could have bought up bankrupt stock, and priced it at their mark up?
Another example of this that I have seen is that B&M Bargains buy in bulk, set a profit margin for the job lot, and when they have attained that margin, they are happy to sell the remaining stock to staff members.
I witnessed them selling fold up camping chairs priced at £10 to store staff at the end of September for 10p - yes, 10p.
It saves them having to store the goods back at the distribution centres, gathering dust until the summer season comes around again.
They were even happy to extend the discount to contractors, and I bagged a full patio table & chair set priced at £100 for £5.
Big business works in mysterious ways . . .
One thing is for sure, if I see Tobacco Reserve at a discounted price in a shop again, I will buy it, open it and spray it in the shop, and if it's 'not right' would demand a refund.
