I think it's pretty obviously a misprint. I think it's the 3750 that's the misprint, and the 1375 is right {so it should have 2750 as its cost}.
My reasoning is thus:
Wildshape is a power available at 4th level, analagous to the Beast Shape Spells.
Beast Shape I {what the first uses of Wildshape act as} is a level 3 spell, with a minimum caster level of 5.
Polymorph, while a possible substitution in the creation of this wondrous item, is of much higher level {so could, of course, be used to support the '3750gp being right' camp, but I digress}, so I'll use Beastshape as the closest, earliest-available analog in price computation.
So, by RAW:
Spell trigger item cost = spell level x caster level x 750gp
{gp value, not = 3 x 5 x 750
cost to create} = 11250gp
charges per day item = cost / { 5 / charges per day}
= cost / {5 / 1 }
= 11250/ 5
= 2250
So by the RAW for Wondrous item creation, assuming a 5th level caster of a 3rd level spell usable once per day, the approximate gold piece value would be 2250. Assuming an extra 500 gp for 'scaling ability' {i.e. emulates higher beast shape spells as the druid gains power}, and one can arrive at a gp value of 2750.
Of course, this is all conjecture, and subject to interpretation, as are all the rules for wondrous item creation, but that's what I think.
