Cala Bona has a few small mini-markets, many of the apartments have a shop on site. Bip supermarket on main street for better selection. If you want a large supermarket nearest is Caprabo on outskirt of Sa Coma, huge selection and reasonable prices (€1 req for trolley) there is a big supermarket in Cala Millor just up from the tourist info office can't remember name. I am sure you will get more posts as Cala Bona is a fave place with a lot of us. Some of us have been many times and love to talk about it ! (me especially)l

Hi - If you have your own car from the airport, you are better off going to Carrefour and stocking up. It is about 5 minutes from the airport and is considerably cheaper than most of the resort stores.
In Cala Millor, CBG qiute rightly says that Caprabo is probably the best choice although the one at Sa Coma is marginally cheaper.
Most of the SIP and BIPs are about the same as SPAR over here in the UK - ie small franchised businesses and so their prices tend to be higher although you can pick up some very cheap drink in them e.g. PAULAS on the front in Cala Bona going towards the Levante.

There's a Caprabo just up from tourist info office in Cala Millor.

There's a SYP Eroski in central Cala Millor where horses stand.

There's a BIP on back road (Na Llambies) in Cala Bona (walk up from Crazy Corner and it's on your left) and one up a side road (off road above) near Marins Playa Apts/Hotel Don Jaime.

There's a big Caprabo in Sa Coma, a Lidl at very far end of Cala Millor and a big SYP Eroski on the outskirts of the resort just after you come thru'Son Severa but you'd probably need a taxi for that one.

Think there's another one near the drop off point for the land train too but can't remember what it's called.

There's also 3 billion Spar shops dotted around Cala Bona & Cala Millor so you won't be stuck for places to shop - try Supermercado C'an Pedro (next to Tom's Bar & Hotel Temi) where you can meet Eileen & Pedro - good prices and Pedro makes a mean sandich to order.

Oh and there's a place called Schlecker next to SYP Eroski in Cala Millor which sells toiletries, household stuff and is quite cheap compared to some places.

Hope that helps.

There's a BIP just inland a bit from the harbour ( I think it's a bip ) walking away from the harbour, archade on left, gift shop on right, very tiny spar up on the right and bip further up on left.
Not massive but had everything you'd need, slightly cheaper than anywhere else in cala Bona
