My point was that there are dozens of sites where someone can purchase the same items at far less cost than Aztec offers. I used Mouser as an example because they are normally thought of as an expensive option for components, and yet they beat Aztec's price in this particular area. If Aztec wants to succeed, the should revisit their pricing and shipping policies. I would much rather give my money to an independent business than to a large corporation, but not when the price differential is that great (approximately 20% higher). If I can purchase single quantities of parts cheaper than Aztec sells them for, then they need to find a new supplier for their bulk purchases.
We looked into the price of that LM35DZ and your instincts were correct. We can actually supply that part for $1.20. The other price was based on some older information. It has now been corrected, however I am not certain what you mean about our shipping prices. Mouser's minimum is $4.99 and ours is $5.00. They offer free shipping over $200, so do we.
