Keith, this is why the contact lens manufacturers give us trial lenses,
i.e. so that you can try a pair at no obligation.
With respect to unopened boxes, the return policies vary. I usually
take back unopened boxes within a reasonable time frame at my
discretion.

Thanks for the info. Im assuming that the balance of acuity is a
possibility. If that does happen to be the case would I of achieved
better vision by having the doctor completely try to correct both
asthigmatisms with lenses to fully correct 1.5 and .75 or likewise
asthigmatisms. I still have 1 full box of each lens and a couple extra
ones lying around. If my doctor did decide to change my perscription
is it possible for me to get a refund on the unused lesnes or unopened
boxes. I also find that the toric lens I have is a little more
difficult to get in and when I first started wearing them did bother me
a little but more so it would be nice to get two non toric, or
spherical I believe they are called, lenses. When I first went to get
fitted for contacts from a different doctor, which was about 3 and a
half years prior to when I actually first started wearing contacts I
was given both Acuvue 2 Toric lenses, or possibly just Acuvue Toric
lenses, so I think I might actually have asthigmatism in both eyes
although I think I rememeber my doctor saying that it has gotten
better.

Im currently wearing Acuvue Advanced -3.25, BC 8.7, DIA 14.0 in one
eye. In my other eye Im wearing Acuvue Advanced for Asthigmatism
-3.50, CYL -0.75, AXIS 020. Could I switch to Acuvue Oasys which Ive
only heard good things about. Do I have too much asthigmatism to
switch and since they are very similiar products can I just order them
using this information or will I have to see the eye doctor again.
Given the contact lens prescription, I can only guess at your
refraction. Your actual astigmatism may be 0.75, or 1.00, or even
1.25. It is also conceivable that you have 0.75 in the right eye, and
1.50 in the left, and your doctor wanted simply to balance the acuity
in the two eyes.
But, assuming that the magnitude of the cylinder is actually 0.75, I
can generally get away with prescribing a spherical lens for amounts of
cylinder that are less than 1.00, assuming that the ratio of sphere to
cylinder is relatively high, i.e. the cylinder component is minor
fraction of the total refraction, as it appears to be in your case.
So, the answer is no, you don't 'appear' to have too much astigmatism
to switch. However, if you are in the U.S., you need to request a
prescription change from your doctor.
