Would you be cool with a bunch of mystery Amazon packages showing up at your house? Sometimes two a week?

 Mike and Kelly Gallivan of Acton tell The Boston Globe the first package arrived in October. They have continued to arrive at a rate of one or two a week, about 25 in all. 

 It's mostly cheap gadgets, phone chargers, and other personal computer items.

 The Gallivans say Amazon told them the merchandise was paid for with a gift card with no sender's name. 

 Two experts say the Gallivans are likely unwittingly being used in a ruse to manipulate Amazon buyer reviews. The anonymous sender is likely writing glowing reviews of their own product.
