This is interesting. If a new report is anything to go by, Apple has added an interesting option for retailers carrying physical iTunes Gift Cards. As you know, iTunes Gift Cards are normally offered in $15, 25, $50 or $100 denominations. The new cards provide for custom denominations ranging from $15 to $500.
These give customers a much-needed flexibility to load their iTunes account with a custom credit of their choosing rather than having to choose between Apple's four preloaded amounts. Apparently one supermarket chain and at least one retailer are rolling these out as we speak...
