| Note:
we respond to all orders with a confirming email and and
estimate of when it will be shipped (today or tomorrow
usually). That email will be sent within hours,
definitely less than a day. Occasionally paypal will
not notify us of an order and we do not know about it.
If you do not get a confirming email for your order within
24 hours, feel free to contact us as it means we do
not know about it. |

| Use
and Astro-Mall
and Astroclassifieds.com
for buying and selling your used equipment.
They are great free sites! Unlike Astromart, there
is no $12 fee to sign up or to change your email address
or other data. (and they still claim it is a free
service.) Even if you post your stuff on Astromart, post
on these too and help them grow. Competition
is a good thing. There are more and more people finding
these sites friendlier and cheaper to buy and sell
on. Besides, Herb has kicked so many people off that
you will have a whole new audience. I was
booted because I politely questioned the high prices of
Astromart ads and their latest increase. His
reply, "You are history" So consider my
website a historic site! Also check out http://www.astronomyratings.com/ and rate the equipment you have purchased so that everyone can benefit. |
