Gibralter tabacco & cigerette prices?

I've been surfing the internet looking for tabacco & cigerette prices in Gibralter!(but not had any luck)
200 B&H, Lambert & Butler, Embassey no1, Amber leaf & Golden virgina?
Also can you just buy in bulk in one shop or would the shop owners report you to the officals?
Or are you better off to buy in many different shops?
Obviously just asking through curiousity!
