Product review (1 stars): This appears to be a bait-and-switch
I didn't get part number 3949237 as advertised.  I got part number 3949247.

Part number (3949247) was listed by other vendors, for a little a $.01 (plus $5.49 shipping), but the reviews were not-so-good, so I did not want part number 3949247.  Therefore, I ordered this one, because the part number listed (3949237) is identical to the one printed on my switch, and I though I would get part number 3949237, and it would be a better buy.  Not so.

As it turns out, they repeatedly advertised part number 3949237, but instead, sent part number 3949247------ which seems to be a bait-and-switch, since it is not mention that the one they will send will be a replacement part for 3949237.  Now I have the same ones (I ordered three) as the ones with the not-so-good ratings, and with a more expensive price tag to boot.

I'm always looking to get the best deal.  This time I was fooled into paying $8.99 each, when I could have paid $5.49 each.  This is a difference of $10.50 ( 3 x $3.50) for three switches.

I hate getting ripped off, and therefore my boycott of DeepDiscountsco starts NOW!!
