Suggestion: We recommend you use gift certificates from either online shopping sites, or local stores in your area, to allow the subjects to easily obtain what they have purchased during the experiment. We recommend you don't use certificates from stores like Amazon which have a wide variety of goods on offer, because in that case, preferences will be hard to determine. Also, do ensure that at one item is your local currency, e.g. U.S. dollars, in order to link the experiment with the real world.

For example, you can buy online gift certificates valid in the U.S. from any of the following stores listed below. Please note, however, that Econport has no relation whatsoever with any of these businesses. These are only suggestions.

 Food:

• McDonald's (Booklets of five $1 certificates)
• Domino's (No more than 5 gift cards, from $5-$100 in value)
• Papa John's Pizza (minimum $10 per certificate)
• Subway (Minimum $5 per card)

 Books:

• Barnes and Noble ($10-$250 per card)
• Powell's ($5-$5,000 per certificate)

 Electronics:

• Best Buy (minimum $5 per card)
