There are Lidl supermarkets situated in Calpe,( on the right hand side of the N332 travelling towards Benissa, just before you arrive at the main roundabout), Calpe, (drive along the coast road from Moraira and when you arrive at the first Mercadona on the right hand side continue past until you come to the signpost on the right hand side), and Denia (this is situated on the left hand side of the dual carriageway as you arrive at Denia from the N332).
These supermarkets are extremely reasonable in price for almost everything, for example wines, beers, dry goods, vegetables, usually of good quality, dairy products, soap products, etc.
Also, every week they feature various other items for sale and each week there is a theme, for example, beach ware, kitchen appliances, fishing gear, artist materials, bathroom fittings, cameras, etc.
To find out what is on offer each week the Costa Blanca News features three pages of advertisements. Lidl will supply bags but charge for them so it is worth taking a few bags with you.
