Redsave.com is a thoroughly disreputable and unscrupulous company. Their customer service is so deplorably bad as to be almost non-existent.
They will debit your credit card account immediately the order is sent irrespective of whether the item is in stock. Their website deliberately makes it difficult for a customer to realise that by making a purchase from them they have joined a so called 'shopping club' whereby £19.95 per month is debited from the credit card account EVERY MONTH THEREAFTER.
They are extremely difficult to contact. They do not answer the telephone. They do not reply to emails. Getting any refund from them is almost impossible and then only after a delay of 2 months or more.
DO NOT USE THIS COMPANY - YOU HAVE BEEN WARNED.
