My favourite place to shop has to be lovehoney.co.uk. The prices are very reasonable and so far I have been really pleased by the quality. Free postage if the order is £20 and over. Discreetly packaged. Plus points on your purchases.
the following I have purchased some months ago as part of a Lovehoney special offer.
