In the US56% of shoppers reported that they were loyal to the same
specialty stores >5 years (American Express Retail Index 1999)About 50% of shoppers were found to be loyal to a single
supermarket (Bell and Lattin 1998) Outside the US
38% is Worchester, MA shopped at the closest supermarket (Thompson 1967)
50% in Christchurch,NZ bought groceries, meat and vegetables at the closest stores (Clark 1968, Clark and Rushton 1970)
25% in Manchester, UK bought bread at closest store (Fingleton 1975)

Store SwitchingâSTOCK UPâ VS âFILL INâ TRIPS
EXAMPLE â Suppose you need to buy 10 units of âstuff.â Which store should you choose?
Kroger (a neighborhood store): a âunitâ costs $4.00. Shopping cost is low (say $1.00). Total acquisition cost is 1 + (10 4) = 41.
Samâs Club (a low-price store): a âunitâ costs $3.00. Shopping cost is high (say $8.00). Total acquisition cost is 8 + (10 3) = 38.

Specifically, how are retailer revenues affected by nearby supermarkets, drug stores, mass merchandisers and supercenters, dollar stores and warehouse clubs?

Multi-Store ShoppingPRICE SEARCH AND âTRIP CHAININGâ
Preliminary findingsBy allowing for search between stores and âtrip chaining,â
we can explain 166% more of shoppersâ spending behavior than travel distance alone.
Together, all retail location variables explain a substantial amount of shoppersâ spending (17.3%).
Retail location findingsSupermarkets lose revenues by locating near warehouse
clubs and drug stores, due to both search and trip chaining.
Supermarkets locating near other supermarkets neither lose nor gain revenues uniformly. It appears that some stores benefit and other stores suffer.

Multi-Store ShoppingCHERRY-PICKING
âInstead of going to the same outlet each week, every week, to complete their grocery shopping, price-price-conscious consumers often visit more than one conscious consumers often visit more than one store in search of special prices â a bargain-hunting store in search of special prices â a bargain-hunting practice known in the industry as âcherry-picking.âpractice known in the industry as âcherry-picking.ââ (Mogelonsky 1994)
Consumer Reports recommends that smart shoppers âscrutinize the food-day ads and âcherry pickâ the scrutinize the food-day ads and âcherry pickâ the specialsspecials,â noting that 20% of its readers show little loyalty among supermarkets (Consumer Reports 1988)

Multi-Store ShoppingCHERRY-PICKING
Size of the cherry-picking segment Only 20% of households donât cherry-pick at all 7% of store visits are made when cherry-picking, so 14% of people
visiting a supermarket are cherry-picking.
Who cherry-picks? Cherry-picking households are either older (lower cost to cherry-pick)
or bigger (higher returns to cherry-picking) Homeownership, stay-at-home spouses and higher incomes all lead to
more cherry-picking
So what? When shoppers cherry-pick, we found that they buy 25% more items
that are on deal and over a third more feature advertised items

We find that cherry-pickers:We find that cherry-pickers:Save an average of $14 on cherry-picking tripsSave an average of $14 on cherry-picking tripsAre more vigilant shoppers, even when they donât cherry-pick Are more vigilant shoppers, even when they donât cherry-pick

Multi-Store ShoppingCHERRY-PICKING
When cherry-picking, do consumers care about being a âsmart shopperâ and feeling good about themselves, or are they just interested in saving money? (research with Suzanne Shu and John Semple)
We find the first evidence of the âsmart shopperâ phenomenon outside of a laboratory
We also find that âsmart shoppersâ save less than those who care only about savings, but are just as happy
