Well just see this site and i amazed when i opened the site.
Here is my review about spending-bitcoin.com,

The interface is very eye-catching, when i opened using my phone it's also mobile friendly,

There are lot of online stores there which accept bitcoin (amazed there are more than 1000 online stores), you can likely find anything you want from there since there are lot of choice (bitcoin hardware, gaming, service, and even charity),

They are also have warned you when you try to choose adult & gambling, so if you are still under age or prohibited to open those sites, better to go back,

On gambling, I've seen you still listed Luckygames.io and 1Xbit, which i suggest you to remove both sites.
The reason are...
https://bitcointalk.org/index.php?topic=1696880.0 Luckygames.io ANN thread and https://bitcointalk.org/index.php?action=profile;u=924703 Here is the main account, which got negative trust from DT since they cheated (modified the ToS to not paying the winnings to their player)
Luckygames also closed now, as you can read from here https://bitcointalk.org/index.php?topic=5256726.0

1Xbit also have lot of negative trusts and unresolved problem, as you can see through here https://bitcointalk.org/index.php?topic=5267172.0 , it'd better to remove their site for now.

You can add other trusted gambling site, as Wolf.bet, Justdice.com, and Bustadice.com because i haven't seen those sites on your site.

You can edit all the choice by using Capital word, so it will looks more professional IMO.

Overall, it's a good site and have many choice about online stores which accept bitcoin
