I wouldn't suggest Spectrocoin. It's shitty service in general and there is some scam accusations sgainst them.
You can try to look at Coingate or Coinpayments.
There is also open source payment proccessor BTCPayServer.org, it's worth to check.
All of these services are easy to integrate, you just have to install their plugin to your website.
Ok, I see thanks for the advice. I would need to take a look at more info on all of them.
But I would probably prefer going with
BLOCKCHAIN.INFO as I often use it and find them trustworthy overall.
@soniaboxer, you have direct amazon links to the products you are just recommending on your website. Amazon doesn't accept Bitcoin's directly until, so I don't think it would be that easy to integrate a BTC payment getway to amazon.
