LONDON (Reuters) - British supermarket chain Sainsbury's plans to double the number of its Click & Collect sites over the next 12 months in response to the increasing popularity of the service as UK shopping habits change. Online shopping is one of the better-performing parts of Britain's retail sector and has become a key battleground for the big supermarkets as they grapple with the growth of German discounters Aldi [ALDIEI.UL] and Lidl [LIDUK.UL]. British shoppers are increasingly choosing the convenience of ordering online and collecting from stores rather than waiting at home for deliveries. Sainsbury's, however, is playing catch-up with rivals Tesco and Asda, the British arm of Wal-Mart Stores . Its Click & Collect groceries service, launched in March last year, offers 100 collection sites but is now targeting 200 sites by May 2017, the company said on Tuesday. The chain's "drive-thru" service allows customers to pre-select a collection time and collect shopping from a refrigerated van parked in a designated area of a store’s car park without having to leave their cars. Market leader Tesco provides click-and-collect groceries from 330 stores, while Asda provides the service from 618 sites. The news on Click & Collect from Sainsbury's comes a day before it publishes full-year results. Analysts are on average forecasting an underlying pretax profit of 574 million pounds ($843 million) for the year to March 12, down from 681 million pounds in 2014/15. Sainsbury's has shown greater resilience to competition from the discounters than its rivals and last month agreed a 1.4 billion pound takeover of Argos-owner Home Retail .
